The International Maize and Wheat Improvement Center (CIMMYT) in Mexico provided training to 471 wheat improvement in-service trainees from 80 developing countries between 1966 and 1988. The principal objective of this training is to strengthen the national research programs in developing countries. In 1988, CIMMYT undertook a follow-up study to determine the program's effectiveness. They mailed questionnaires to 324 program alumni, who had been back on their jobs for at least 1 yr. Next, they evaluated completed questionnaires returned by 142 trainees from 45 countries. Survey data indicated that 74% of respondents work for their government's research and extension services. More than 50% of the former trainees worked directly with wheat (Triticum aestivum L.) improvement work. Overall, former trainees were generally pleased with the training course's structure and content finding most subjects relevant to their work. Nearly 94% of former participants indicated the course inspired confidence in their abilities, and in turn, had a positive impact on their quality of work. In conclusion, the consequent work behavior of former trainees appeared to be consistent with the training objectives and philosophy being pursued by CIMMYT, which emphasizes the practical application of skills.
