There is much left to be done after evaluation programs have been developed. Successful operation is frequently jeopardized by sloppy implementation. Too frequently, a statement of procedures is distributed, and evaluatees and evaluators are left to their own devices to understand the procedures and become prepared to fulfill their roles in the process. Implementation in large school systems requires intensive thought and well-designed strategies. Whether large or small, however, school systems should consider carefully the following as implementation tools and techniques: (1) a good handbook of evaluation procedures, (2) an audiovisual program to supplement the handbook, (3) orientation sessions to introduce the program to the staff, (4) in-service meetings in smaller groups, and (5) skill-development sessions.
