The Word Workers Achievement Tests book is a carefully structured series of tests to monitor student progress. The tests align with the Activity Books of the series, and are designed to provide a familiar and non-threatening form of assessment. Word Workers Achievement Tests allows teachers to instruct, and provide an encouraging record of progress.

The Reading Freedom 2000 Diagnostic Handbook should be used to place students at the correct level in the program. In order to work successfully with the Word Workers Activity Books, teachers should refer to the Word Workers Teacher Resource Book and monitor student progress with the Word Workers Achievement Tests book.
