Program Evaluation 201

Lessons Learned: What Jack Should Have Asked His Evaluator

• Ask for all descriptive statistics of pretest data, not just the means. Make sure you also receive the standard deviations.
• Also make sure the evaluator includes a discussion of all descriptive statistics.
• Finally, be sure to ask for pretest data as early in the program cycle as possible preferably as soon as they are collected. This information will be very helpful, you may want to adapt your program based on pretest results.
