CBEST Pass Rate, Format & Study Guide

The CBEST has three sections: Reading (50 multiple-choice questions), Mathematics (50 multiple-choice questions) and Writing (two essays); each section is scored from 20 to 80 (CBEST test page, CTC/Pearson). You pass with a scaled score of 41 on each section and a total of at least 123; a section score as low as 37 still counts if the total across the three sections reaches 123, and passing scores do not expire (CTC leaflet CL-667). This portal is a study aid: its 120-question practice set uses multiple-choice items only and does not simulate the two Writing essays, so use the 70 percent result as a self-check, not a score prediction.

Passing the CBEST is one of the accepted ways to meet the basic skills requirement that many California credentials and permits require.

This portal groups its practice by those subareas: critical analysis and evaluation, comprehension and research, estimation and measurement, computation and problem solving, numerical and graphic relationships, and the language skills behind effective writing.

Anyone may register. The CTC accepts several ways to meet the basic skills requirement, and the CBEST is one of them; check which option your credential program or employer expects.
