CAT (California Achievement Test)

The California Achievement Test (CAT) offered by Academic Excellence is an online standardized test that homeschool families can administer at home, timed or untimed. It provides percentile scores and grade equivalents in reading, language, and math, giving parents external data for progress reports or state requirements. Families appreciate the straightforward registration, quick results, and ability to test multiple children on their own schedule. There is a per-student fee, but compared with arranging in-person testing, CAT can be a convenient, relatively affordable option.
