This educator's guide to the California Assessment Program's English-Language Arts test describes what California's new reading and editing tests do and do not measure. The guide states that each test form consists of one reading passage from literature, science, or history-social science followed by a variety of questions on word meaning and comprehension (with emphasis on inference items). The guide points out that the new test deals with more difficult content and more complex thinking than the original did, and also that special efforts were made to include passages that would appeal to the diversity of ethnic groups in California. The editing test in the guide is based on student essays and consists of multiple-choice questions that assess the most commonly occurring errors in student writing. The guide includes three illustrative reading and editing test forms. (KEH)
