Fifty profiles of published tests of writing proficiency are compiled alphabetically with a thorough guide to indirect assessment of writing skill. The profiles are designed to facilitate a general screening of available test options. The elements included in each profile are as follows: test name, publication date, publisher, administration time, grade levels, traits measured, writing sample, appropriate uses, and reliability and validity information. A final consideration in test selection relates to ease, efficiency and cost of use. A brief guideline is presented to help consider the test logistics and to better analyze the published user's manual. (Author/CE)
