This paper reports on an independent review of two examinations designed to assess teacher competencies: the Praxis Series and the Content Mastery Examinations for Educators (CMEE). The review was ordered by the Montana Department of Public Education in order to decide which battery of tests would replace the National Teacher Examination (NTE). The paper, which is a point-by-point examination of the Prasix Series and the CMEE, covers: (1) a general description of each examination; (2) test content; (3) accommodation for people with disabilities; (4) development; (5) technical and psychometric aspects (validity, bias, reliability, and score reporting); (6) strengths and weaknesses; and (7) a discussion of each test series. The paper concludes with a general discussion on the role of assessment of knowledge and skills in various professions. Findings of the study indicate that the CMEE and the Praxis Series are both appropriate assessment batteries; both have been developed and studied to assure validity and reliability. However, during the study, while technical assistance was readily available from the National Computer System staff regarding CMEE, getting information on the Praxis Series from Educational Testing Service was more cumbersome. The study concludes that assessment of knowledge of candidates for teaching certificates must serve the state (representing the children) and the teaching profession by assisting to certify only qualified candidates. The process should be kept simple and efficient for candidates, assessing the areas the state and profession deem necessary, and variables such as score reporting, cost, and accessibility ought to be considered when making decisions on assessment instruments.
