Each ATLAST teacher assessment consists of approximately 30 multiple-choice items designed to measure teacher knowledge in a specific content area. The teacher assessments measure all of the content included on the corresponding student assessments, as well as additional science content necessary for teaching the student content (as noted in the content clarifications). In addition, all questions are set in instructional contexts, with some items requiring teachers to analyze student thinking or to choose among instructional responses to student thinking.
The development of the teacher assessments is described in Teacher Assessment Development.
Properties of each of the teacher assessments, including evidence of reliability and validity, are described in Teacher Assessment Characteristics.
Information on accessing the assessments for review and/or administration is in Accessing the Teacher Assessments.
