Test Scores

About STAR

Each year all public schools in California participate in the STAR (Standardized Testing and Reporting) accountability system, whose purpose is to measure academic performance and growth. The State of California shows the results of these assessments when it releases the API scores for all schools in the state. The Academic Performance Index (API) is part of California's Public Schools Accountability Act (PSAA). It is a numeric index (or scale) that ranges from a low of 200 to a high of 1000. A school's score on the API is an indicator of a school's performance level. The statewide API performance target for all schools is 800. A school's growth is measured by how well it is moving toward or past that goal. A school's base year API is subtracted from its growth API to determine how much the school has progressed in a year.  


We believe strongly that students should be successful on this assessment. While we understand it is a single measure, Stanley continues to look into these scores using web-based tools such as Data Director. We use these findings along with other multiple measures of student progress to analyze and disaggregate data (Data-Based Inquiry). Stanley’s goal for this data based inquiry is to solve problems, find gaps, and improve our practice. We are pleased to say that our success on assessments like STAR is due to high quality instruction and the strong partnerships that our schools have with parents and the community.

The CSTs are a major component of the STAR program. The CSTs are developed by California educators and test developers specifically for California. They measure students' progress toward achieving California's state-adopted academic content standards in English–language arts (ELA), mathematics, science, and history–social science, which describe what students should know and be able to do in each grade and subject tested.

Visit the STAR CST Blueprints page on the California Department of Education Web site to see the CST blueprints.


Who Will Take the CSTs?

Students in grades two through eleven take multiple-choice CSTs for various subjects. Students in grade seven complete a writing assessment—the CST for Writing—as a part of the CST for ELA.
