About 3,000 educators have participated in Educ 521 human relations recertification programs sponsored by the Minneapolis Public Schools (MPS). In February 1975, the 755 participants who had processed their recertification forms were mailed a questionnaire to determine overall program effectiveness, differences among programs, and directions for future human relations education. Based on the post-program reactions given by 75 percent of the participants, it was the evaluator's opinion that, considering the conditions under which the program was operating, the 521 program was valuable. Not all participants became more competent in the areas specified by Educ 521; in fact, a substantial percentage indicated that the program was not helpful. However, two-thirds of the participants did say that the program helped them increase their understanding of various ethnic/cultural groups, biases, and power/powerlessness. Three-fourths said they improved their communication skills; about half said they learned skills that could be used in the school setting; and about half said they interacted differently in the school setting as a result of the 521 program. Recommendations were made to offer a variety of 521 programs that would meet the different needs of potential participants, define clearly the goals and activities of each program, offer voluntary in-depth human relations programs beyond the 521 program, emphasize real experiences in all programs, and explore some new approaches.
