Lisa is 8 years old; according to her brother Bart, Lisa is 2 years and 38 days younger than him. This presumably places her birthday as being on May 9, given Bart's birthday is April 1. While she was shown as being born during the 1984 Summer Olympics in one flashback episode ("Lisa's First Word"), given that the characters in The Simpsons generally don't age, no specific year for her birth can truly be given (besides "always" being born "about 8 years ago").

Lisa is an extremely bright girl, with an IQ of 159. Officially, her highest grade is an A+++ which she earned by cheating in a test on The Wind in the Willows. (She later re-marked the test as an F.) Once, when she was unable to attend school due to a teachers' strike, she suffered a sort of "school withdrawal" and invented a perpetual motion machine; Homer chastised her for this, telling her that in the Simpson household "we obey the laws of thermodynamics!"
