ab 104

Assembly Bill (AB) 104 requires school districts to implement policies that give students opportunities to counteract the impact of the pandemic on students' academic achievement and graduation credits. The new law, which went into effect on July 1, 2021, includes options that include requesting retention for eligible students, changing grades to a Pass or No Pass for students enrolled in high school last year, and waiving local district graduation requirements that exceed the state credit and course minimums for students who were juniors or seniors in the 2020-21 school year.  

Learn more about AB 104: AB 104 Slides

Complete the form below if you'd like to request a grade change. Students now have additional time to request grade changes from letter-based grading to Pass/No Pass. Please contact your counselor with any questions.
