PBA's (Performance Based Assessment) and CRT's (Criterion Referenced Test) are administered by Glendale Union High School District to measure achievement in courses.  On a PBA, students typically write an essay or create a product.  A CRT is a multiple choice test. The results are often used as final exams and count as part of the course grade.  PBA's and CRT's are usually administered at the end of the semester.  Contact course instructor to see when your PBA or CRT will be given.
