Andrea is a dedicated high school student at West Beverly, who also serves as the editor of the West Beverly Blaze – the school newspaper. Engaging in a plethora of extra credit programmes and volunteering, the girl living out of district is set on reaching her goal of an academic scholarship to Yale University. Andrea is incredibly sweet and has a big heart; she is also a very logical person, which leads to her feeling socially awkward and therefore adopting a more shy nature when trying to talk to other students.
Her logical nature can leave her very blunt in her emotional expression, but she finds acceptance and a sense of self in her relationships with the gang. Her close friendship with Brandon Walsh, although their relationship is never truly platonic, changes her course somewhat – for the better – as Andrea starts engaging in the high school social life and makes friends for life.
Andrea spends her time at West Beverly working toward academic stardom and has little time for anything – or one – else. The down-to-earth nature of the Minnesota twins has a deep effect on a number of students, but Andrea's lifestyle is immediately altered by Brandon Walsh's presence in her life. After initially assuming he is superficial, Brandon makes an effort to explain his behaviour to Andrea and accidentally learns of Andrea's family situation, with her living out of district and he is there for her, the two of them developing a close bond. While maintaining they're just friends, they have an undeniable chemistry, which neither seem willing to act upon for a year.
Andrea begins to lessen her at times intense black-and-white behaviour towards others and starts opening up to the possibility of making friends at her school. This starts with Brenda, who Brandon encourages to include Andrea in a mother-daughter fashion show, hosted by Kelly's mother. While Brenda is reluctant at first, she quickly finds that they all get along well. Andrea provides a different perspective on Kelly's difficult home life when she tells Kelly that she considers her amazing, for leading the life she leads while taking on such an adult responsibility, which she shouldn't have to deal with. When Brenda later wishes to do something fulfilling in Beverly Hills, Brandon sets her up with Andrea, who works at a teen helpline.
This brings Andrea closer to Brenda, although the two think they are very different people, they find that they actually have a lot in common when it comes to what's real in life. They work together to save a girl and the experience brings about a bond that is furthered when Brenda invites Andrea over for a slumber party with the other girls, where Andrea also becomes closer to the other girls. Andrea and Kelly especially find new understanding for one another, allegedly two people on the opposite ends of the high school social strata spectrum. Though socially awkward and frequently nerve-wracked that she won't be included, Andrea continues to take chances in her social life, ending up studying with Steve Sanders – and unexpectedly they make out.
Andrea and Brandon continue to grow closer, both hesitant to act on their strong attraction to one another. This hesitancy results in them not going to the Spring Fling together and Brandon accepting Kelly's proposal to go as friends, which leaves Andrea incredibly jealous. After she has a Carrie-esque dream of bringing a chain saw to the dance to attack 'Spring Princess' Kelly, Andrea realises the dance does mean a great deal to her and decides to attend, finding that the group of friends is growing ever stronger and that she is very much an important part of it. Kelly gives Andrea her Spring Princess crown.
When Jim announces the Walshes will be returning to Minnesota, Andrea tells Brandon they should sleep together, creating a lasting memento of their bond as he leaves. Their plans at the Peach Pit are thwarted by Kelly (who knew about their plans) throwing the Walsh family a farewell party. Andrea and Brandon are startled, but also mutually backtrack their plans as if the intervention was a sign of sorts. Due to the outpouring of love, Jim reconsiders and the Walshes remain in Beverly Hills.
The Blaze signs out for the summer with a meeting and cake at West Beverly, where Brandon tries to talk to Andrea about what happened between them. Brandon doesn't seem willing to immediately let go of what happened, but Andrea insists that it would be best if they just go back to being friends. Andrea is tutoring kids over the summer and decides to enroll in a summer drama class, which Brenda and Donna also take. Andrea also approaches Brandon to become a big brother to a kid at the center where she tutors kids. When Brandon finds out his mother is abusive, he seeks out Andrea and together they help find Felix a solution. The drama class teacher, Chris Suiter, becomes romantically interested in Andrea, much to Brenda's chagrin, and they share a kiss.
Andrea agrees to go on a date with him, but finds out that he has a girlfriend, with whom he is moving out to L.A. permanently. Andrea's heartbroken and throws him out. Andrea goes to the Beverly Hills Beach Club end of summer loo-ou, where Brenda comforts her and the girls reconcile their friendship. The whole gang goes on a trip to Yosemite before the end of summer, but end up stuck in a cabin during a torrential downpour. Everyone gets on each other's nerves and starts discussing what is really important in life, when a newlywed couple next door involve the gang in their problems. Andrea argues that the meaning of life is love. After Dylan saves Brandon's life on a morning hike, unbeknownst to the group, Brandon's near-death experience reaction is to give Andrea a giant hug.
Starting her junior year, Andrea returns as the editor at The Blaze. Though she was adamant that she and Brandon should just stay friends, Andrea is visibly jealous when Brandon takes an interest in new girl Emily Valentine, who also starts working at the paper to be closer to Brandon. Although it's hard for Andrea to see Brandon with someone else, she never tells him how she really feels or changes her mind about wanting to be with him. They continue to be friends and Andrea attends the Walsh barbecue where Emily is invited, too. Later, she and Brandon watch the girls perform at 'Hello Day' together. Andrea continues to hang out with the gang, spending an evening at Casa Walsh with everyone and meeting the twins' cousin, Bobby. Brandon accidentally gets Andrea worried when he submits her work for a journalism competition and she wins, prompting an interviewer to want to visit her home, though she lives out of district.
The girls help decorate Andrea's area of her grandmother's Beverly Hills apartment, although Andrea's grandmother Rose proves another obstacle as she is tough on Andrea and refuses to lie about the situation. Brandon is especially concerned, visiting multiple times and supporting Andrea emotionally throughout the crisis. Andrea has to move in permanently with her grandmother to stay at West Beverly and she agrees to do so when she and her grandmother work through their family issues. The experience ends up bonding Andrea further with the gang as they help her and celebrate her staying at West Beverly with a cake at the Pit, showing Andrea that she has made true friends at school. Andrea and Brandon represent The Blaze in a school event to unearth a time capsule and later bury one themselves to mark the death of fellow student, Scott Scanlon.
A while after this tragic event, Emily invites the gang to a secret underground club, and Andrea hesitates to attend, eventually agreeing saying she can write about it, but really it's because she's feeling threatened by Emily. Steve and Andrea are both late and go together, having a tough time figuring out where the location is. Steve presses Andrea about being jealous of Brandon & Emily, and he encourages her to 'stop apologising for who she is and get in the game', and Andrea reluctantly admits that she is insecure. Before Andrea can get the scoop on why the police are breaking up the party, she and Steve run into the drugged up Emily and Brandon. Brandon kisses Andrea and she freaks at his behaviour. The next day, Brandon confides in Andrea about how Emily spiked his drink and apologises to her for his behaviour. Andrea accepts and seems relieved that Emily and Brandon are over.
Emily and Andrea generally have an adversarial relationship, with Emily well aware of Andrea's feelings for Brandon. Andrea is a friend to Brandon following the euphoria incident, but, despite Emily telling Andrea she and Brandon had sex, Andrea reaches out a hand in friendship to Emily when Emily feels left out of the group, an experience Andrea can relate to. Once Emily starts harassing Brandon, Andrea is the first to point out that there seems to be something going on with Emily and that she needs help rather than being rejected by everyone for her behaviour. Andrea doesn't enjoy the holidays as she's Jewish, but her parents celebrate neither occasion. She spends her first Christmas ever at the Walsh household with everyone and happily takes her first ever turn at telling Santa what she wants for Christmas. Andrea and Brandon's intense friendship continues as Andrea meets a celebrity ice skating champion who she admires, but recoils upon realising Brandon is dating her.
Andrea and Brandon work together to expose the use of steroids on the West Beverly track team, where Andrea puts herself in the line of fire from the jocks in order to shield Brandon from retribution. She takes it upon herself to lead the fight against the school board's unrealistic sex-ed policy by distributing free condoms at West Beverly. She and Brandon get into a fight and he calls her a hypocrite because she's never had sex, which embarrasses and hurts Andrea. Brandon later apologises for his rude behaviour and they make amends. They continue to be friends and spend time together, while Andrea's insecurity about whether or not she's really part of the gang abates.
The summer before her senior year, Andrea volunteers as a camp counsellor for kids at Beverly Hills Beach Club. She meets a Cameron who's deaf while working at the beach camp and convinces his hesitant mother to allow him into the camp, as Andrea knows sign language. He flourishes and his mother is incredibly grateful to Andrea. Andrea starts dating former Blaze editor Jay Thurman, which everyone only learns when he shows up at the Pit for their date at the beginning of summer. They become enamoured quickly and when Jay is leaving for Houston for the summer to attend the RNC, he asks Andrea to come with him. Andrea's ecstatic at the opportunity, but falters when Brandon (with ulterior motives) gives out to her for leaving Cameron behind, although Cameron's mother is very understanding and just grateful that her child could get that experience altogether.
Andrea's upset with Brandon, who tells her he really wants her to stay for him, because he'll miss her. Andrea's confused and Brandon kisses her, at which point her hurt becomes anger and she lashes out, saying he had his chance when she was single. Brandon attempts to change her mind anyway, but Andrea rejects him. He later apologises to her, saying he was in the wrong and she forgives him. All the same, Andrea decides she wants to stay at camp for Cameron. Jay and Andrea care about each other so much that they decide to start a long-distance relationship.

- —Andrea accuses Gil Meyers of being sexist
Andrea starts her senior year buoyant, but is angry when the new Blaze faculty advisor, Gil Meyers, suggests demoting Andrea to co-editor alongside Brandon. She accuses Gil of being sexist and fights with Brandon, telling him he is less competent to run the paper than she, who has spent all her energy in her high school career working at making it a success. The situation makes Gil question his self-proclaimed feminism, fuels Brandon and Andrea's ever-growing sexual tension, but ultimately is resolved when everyone has a frank discussion about what they learned from the situation. Andrea agrees to be co-editor with Brandon and start fresh as a team their senior year. Gil becomes a big part of Andrea's senior year, when she starts applying for her colleges and trepidatiously prepares to apply to Yale. Gil is an alumnus and Andrea cares a lot about what he thinks of her chances.
Andrea and Brenda team up to help freshman Sue Scanlon when she accuses Gil Meyers of sexual assault and with Donna's help, uncover that Sue was being abused by a man in her family. Andrea's involved in a hit-and-run, which leaves her with a broken leg. Brandon is there for her and the gang all visit her at the hospital. Andrea is quickly back at school and eagerly following an investigation into a break-in at school, unaware that Steve is the culprit. When Steve confesses Andrea is hurt thinking he only spent time with and helped her to stay ahead of being found out, but Steve apologises for his general behaviour and says that is not the case at all. As Christmas nears, Andrea gets her answer from Yale — she's been accepted! But she also gets a cowardly letter from Jay breaking up with her, crushing her acceptance joy. Brandon is livid on her behalf and, after being dumped himself, he and Andrea watch a film together and kiss. Andrea feels she's being used as a rebound, while Brandon accuses her of the same but they make up.
Andrea attend hypnotherapy to remember who ran her over as it's haunting her and through a lucky coincidence, Brandon and Steve's drag racing leads them to a dangerous criminal who happens to be the culprit. Along with Dylan, the guys help Andrea catch the perpetrator, leaving Andrea finally able to put the trauma of her accident behind her. She and the girls go for a weekend spa where Andrea comically finds it hard to just... relax. Andrea discovers that Jordan has been accepted to Yale as well when she attends a mixer for future students, feeling out of place until running into him. Jordan sends her faxes and Andrea thinks he's great. After a while they start dating. After Dylan's father dies tragically Andrea, along with her friends, try and find the right way to be there for Dylan. Andrea comes up with the idea to have a profile on Dylan in The Blaze, which Brandon cautions her against. She visits Dylan and, although he balks at the idea, Dylan later tells her it might help him to write down what happened to him.
Andrea and the girls (and David) have fun at Magic Mountain for Senior Ditch Day, where Andrea and Donna bond over being fellow virgins as Andrea's scared of going on a rollercoaster. Andrea and Jordan are to attend Senior Prom together, but he gets sick and Andrea calls Brandon in as a substitute. They have fun at Prom and Brandon asks Andrea to dance, although he doesn't dance. In spite of dating Jordan, Andrea and Brandon's visit to Tony Miller's vacant hotel room prompts her to suggest she and Brandon have a little fun. Afterwards, Andrea's a bit embarrassed that Brandon put the kibosh on them going further, but realises she just feels like doing something wild, possibly after being so focused and diligent for so many years. Naturally, she is selected as the Valedictorian and frets over her speech and whether she'll attend Yale. Brandon helps Andrea out, but Jordan later suggests to Brandon that Andrea's reconsidering Yale because of her feelings for him. Although this isn't true at all and Brandon has a bit of egg on his face, there is something between them that both of her boyfriends noticed, which is never resolved in spite of their three years going back and forth with an intense, sometimes romantic relationship.
Andrea wrestles with whether to attend Yale or CU, and ultimately decides, for financial reason, to give the Ivy League a miss and stay in Beverly Hills with the gang. Andrea, Kelly, Brenda, and Donna make an effort to pledge the Alpha Omega sorority. However, when Andrea was told by Leslie Sumner to downplay her Jewish heritage, Andrea is obviously offended and dropped out of the running. Leslie later apologized, stating she herself was Jewish, and they made up, though Andrea did not return to sorority life.
Andrea forged a bond with Donna Martin when they shared with one another their decision to wait to have sex. Andrea eventually has sex with her RA, Dan Rubin, which becomes a part of the issue leading to a minor tiff between her and Donna. Andrea and Brenda find themselves on opposite sides when Brenda joins a group which attempts to free animals from a CU test lab. Andrea works at the facility and feels betrayed by Brenda since the lab doesn't actually harm animals in the first place. This season shows Andrea growing closer to the girls in the 90210 gang, with the famous Kelly/Brenda/Donna trio including Andrea, who was previously mainly close friends with just Brandon and Brenda. She forges her own strong bonds with both Donna and Kelly, which last throughout the show's run.
Soon after starting her relationship with Dan Rubin, Andrea meets Jesse Vasquez at Jim and Cindy Walsh's 20th anniversary party and the two click instantly. While still technically with Dan, Andrea begins a relationship with Jesse. She breaks up with Dan who, still in love with Andrea, makes racial comments toward Jesse. Dan eventually moves out of the dorm and Jesse and Andrea continue to date. This leads to the most controversial, and unexpected, storyline development in the character's history. Andrea Zuckerman, having slept with Jesse only once without protection, soon finds that she was pregnant.
This development was designed to coincide with Gabrielle Carteris's real life pregnancy, and allowed the issue of teen pregnancy to be explored fully by using one of the series' regulars, not to mention the most unlikely member of the group. After considering an abortion, Andrea eventually decides to keep the baby, which leads to a close connection with Kelly Taylor, who helps Andrea make her decision. Andrea marries Jesse in a civil ceremony (and in one of the few times that her family is shown) and, after a short pregnancy that ends in the premature delivery of their child, she gives birth to a daughter named Hannah Zuckerman-Vasquez.
After months in the hospital, Andrea and Jesse are finally able to take the baby girl home. Andrea's early season 5 storylines were mostly limited to minor daycare issues, and the struggles she faced as a young mother trying to juggle a new marriage, child, and keeping up her always high marks in college. The early marriage and child story, while a high point for the character a season before, began alienating her from the gang, and Andrea's character was beginning to fade into the background.
Attempts were made during the second half of the season to inject some life into Andrea's waning story. She was thrust back into the political arena, sharing screen time once again with Brandon, a move designed to keep her more involved in campus life, and remind audiences of her once strong political passions. Her marriage was thrown into trouble when she and Jesse had difficulty getting past their religious differences; she being Jewish and he being Catholic. Later a complete physical makeover of the character was allowed; though she'd already shed the glasses a year before, Andrea's hair was suddenly blonde, and she was allowed to wear more fashion and body conscious wear, perhaps in an attempt to visually mesh her with the rest of the women on the canvas. All aspects of the once socially awkward, borderline "nerd" were now wiped clean.
Andrea is given another unexpected story when she begins to cheat on her husband with medical intern Peter Tucker, a man who tried to pick her up at the laundromat when he assumed she was little Hannah's babysitter, not her mother. She throws away the telephone number he gives her, but several episodes later, after running into him again at the laundromat, and with her marriage in serious trouble, she decides to finally call him. This begins a torrid affair, with the two sneaking around at work together, and later going as far as booking their own motel room for sex. Things come to a head for Andrea when she, along with Jesse, run into Peter and his wife Adrian, and they all end up having dinner together, at which time Andrea and Peter share a mutual fantasy that paints them as silver screen dance legends Fred Astaire and Ginger Rogers.
Andrea finally decides she is in love with Peter, and informs Peter that she plans to leave Jesse for him, and she expects him to do the same. Peter, taken aback, changes colors, and tells Andrea that he has no plans to leave his wife, and that he's happy with their "arrangement". Andrea, livid and devastated, ends the affair, and is comforted by friend Dylan McKay, who by chance had found out and confronted Andrea about the affair weeks earlier. Eventually both Andrea and Jesse confess to having an affair, he with a fellow law clerk while away on business, which seems to be the end of their year long marriage. But despite a mounting custody battle, and deeply hurt feelings, both decide that their family is worth them trying to find their way back to each other. Andrea also fulfilled a life-long goal when she was able to appear on Jeopardy! in the show's 5th season. It is suggested by the end of the episode that Andrea wins.
At the end of the season, Jesse received a clerkship at Yale Law School and Andrea decided to transfer to Yale as well to enter their pre-med program, a plot decision necessitated by Carteris' decision to leave the show. This represents a full circle arch with the character, who was shown to be pining after Yale ever since the high school years, and after she was actually admitted into the school but declined due to high tuition costs and an ailing grandmother at the time. After a tearful goodbye with her friends, she is shown finally driving off to her dreams, family in tow, as she remembers brighter days from high school.
Andrea comes back into town for Steve's 21st birthday party on the Queen Mary, which is thrown by Prince Carl (a childhood friend of Clare's). While showing photos of Hannah to Kelly, she reveals that Hannah is 2 years old and Jesse loves being at Yale.
Andrea also returns for the gang's five-year high school reunion, where she caught up with those still in the area and met the new faces. However, all was not well back home, as she and Jesse were planning to divorce. Andrea attends Donna and David's wedding, participating in Donna's bachelor party. She is divorced, but happy with her life.
