<P> In her first appearance in Good Morning, Miss Bliss, Lisa plays a more secondary role than she later would in the later incarnations of the series . She attends John F. Kennedy Junior High with Zack Morris and Samuel "Screech" Powers . </P> <P> Throughout her high school years in Saved by the Bell, Lisa spends most of her time fighting off the affections of Screech, who is relentless in pursuing her (and eventually wins at least one date with her) and has been doing so since they were in Kindergarten . Despite her irritation with Screech, she values him as a friend, and eventually comes to admire Screech's nobility when he abdicates his position as the class valedictorian in favor of Jessie Spano, who had a slightly lower grade point average than he did, but valued the position more . Lisa even went to the senior prom with Screech when she felt sorry that no one would go with him, when he promised to respect her comfort zone and not ask her, but she decided that she wants him to be her prom date . Most of Lisa's time is spent in the company of schoolmates and fellow cheerleaders Kelly Kapowski and Jessie Spano . </P> <P> Unlike the rest of her friends, Lisa does not have a long - term relationship during high school (despite having countless dates), although she has a short term romance with Zack Morris in the episode "The Bayside Triangle," much to the chagrin of Screech . To keep his friendship with Screech, Zack must break up with Lisa . However, this is forgotten about in following episodes . "Screech's Spaghetti Sauce" involves Screech on a date with a girl who is impressed by him, causing Lisa to be in a state of disbelief . </P> <P> Upon graduating, Lisa is accepted into the Fashion Institute of Technology in New York City . Lisa only makes one guest appearance in Saved by the Bell: The College Years when she visits her former classmates Zack, Screech, Kelly, and A.C. Slater at California University in the episode "Wedding Plans", after hearing of Zack and Kelly's engagement . In Saved by the Bell: Wedding in Las Vegas, Lisa and Jessie were Kelly's bridesmaids for her wedding to Zack . Lisa returns to Bayside High along with Zack and Slater in "Goodbye Bayside: Part 2" (from Saved by the Bell: The New Class), where they are reunited with Screech (now working at Bayside on a work - study program) and their principal Mr. Belding when the school is under threat of being torn down by an alumnus . </P>
