Many educational professionals have some knowledge of assessment practices, ranging from principles of test development and use to the practices associated with the use and interpretation of standardized and teacher-made tests. The skill levels associated with many important student assessment principles are, however, not consistent with the Standards adopted by professional organizations. Various standards that have been developed and endorsed by professional associations in education are important documents and they provide excellent guides for the professional development of educators who work with assessment issues on a regular basis. Assessment skills and knowledge of counselors, principals, and teachers are lacking in some important areas while in other important areas these educational professionals are highly skilled and knowledgeable.
