Studies and reports on functions and training of educational media personnel are summarized, and recommendations based on them are presented. Most of the studies catalog specific tasks performed by different types and levels of educational media personnel, analyze the nature of the tasks, classify them as being most appropriately performed by "professional" or "non-professional" personnel, group them into job clusters, and recommend levels of training or education for each. Recommendations include: 1) differences in position titling and functions should be reconciled; 2) recommendations from existing studies should be used rather than augmented by further studies; 3) standards for training media personnel should be agreed on; 4) the quality of new media personnel should be improved; 5) an official statement of professional aims and conditions should be prepared; 6) national certification guidelines should be prepared, and 7) provision for on-the-job and continuing professional education should be made.
