This document was developed as a resource for implementing the teaching of writing in adult education programs. Based on curriculum, assessment, diagnosis, prescription, instruction, evaluation, and classroom management. The program is presented in a 12-step systematic sequence. The steps are the following: (1) develop/customize/adopt a writing skills curriculum; (2) design a locator that can help the tester determine the student's status; (3) design assessment instruments that determine to what extent a student needs writing instruction; (4) provide initial information about writing skills to the student before diagnosing the student's writing strengths and weaknesses; (5) diagnose the student's writing; (6) prescribe materials and modes of instruction to meet the student's goals; (7) instruct students based on each student's prescription; (8) provide inservice workshops for teachers; (9) provide both formative and summative evaluation; (10) evaluate the program every six months; (11) devise a recordkeeping system; and (12) develop a classroom management plan. Samples are provided. Techniques for managing the diagnostic-prescriptive process and a brief bibliography conclude the document. (KC)
