Many school districts face the problem of evaluating new programs to train students in ethics and moral decision making. Using conventional personality tests in program evaluation may be helpful, but probably will not provide measures for the attitudes that are targeted by the intervention. The method of equal- appearing intervals developed by L. Thurstone (1959) provides a viable solution for this problem. How school districts could use this type of scaling to measure attitudes specific to the design of character education programs is discussed. The relative simplicity of Thurstone scaling means that most schools could develop and administer this method in-house. The relative ease of construction would allow school districts not only to measure the effectiveness of an intervention but also to identify children who might be best suited for character education programs.
