REGISTRATION IS CURRENTLY CLOSED!  Our next registration will be held in August for all programs.


It’s not too late to earn your high school diploma!

Vacaville Adult School provides an academic environment and support to help you earn your high school diploma and reach that goal. Adults who wish to enroll will need to report to the scheduled registration days listed below.  Please arrive promptly at scheduled registration time.  If you are a new student, please bring a copy of your most recent transcript to registration. 


The registration process will consist of two components: 

1.  Registration/Orientation

2.  CASAS Testing. 


The registration/orientation process will last approximately one (1) hour.  Registration will consist of completion of all registration paperwork and a short orientation.  During registration, all students will be given a CASAS test date.  ALL students are required to complete CASAS testing in order to be eligible to enroll in classes.  Please allow up to two (2) hours for CASAS Testing. If you have any questions about the registration process, or if you are unable to make your scheduled registration day, please call 707-453-6018. 


Please be advised- due to the changes in the enrollment process, we will no longer be accepting enrollment after the second week of classes.  The final CASAS testing date for the Fall semester will be Thursday, September 6, 2018.  The final CASAS testing date for the Spring semester will be Thursday, January 24, 2019.  Any students that have not completed their CASAS testing by these dates will be dropped.  Enrollment for ALL high school diploma classes (including VOLA classes) will be closed for the semester after the final testing dates.


All classes held at Muzetta Thrower Adult Education Center (Country High School).


Effective the 2018/2019 school year, Adult Education classes will begin running on the semester system. We will also offer the option to take multiple classes per day.  Please see "Fall Semester" and "Spring Semester"  for more information.
