This manual, designed for secondary school counselors, is based on the concept that professional improvement can be accomplished mainly by self-evaluation in conjunction with support from one's own colleagues. Some of the purposes of the manual are to: (1) produce a tool by which the new counselor can conduct his own self-evaluation; (2) provide a vehicle for the experienced counselor to use as a self-review; (3) provide guidelines for the development and improvement of a guidance department; and (4) aid in periodic self-evaluation, self-learning, and self-improvement. The manual includes samples of self-administered evaluations and an extensive bibliography which counselors may use to aid in their self-evaluation. (Author/EK)
