Forms used for data collection in the Cornell-OEO Project fall into the categories of recruitment and selection, family assistant training, in-service training, supervisory records of family assistants, service-family contacts and visits, reports on visits to Cornell-OEO Project, work with groups outside the project, and analysis forms. Twenty-five forms are included with a statement of their purpose, use pattern, and by whom they were to be completed. Some of the problems encountered in data collection were timing, data transmission delays, language barriers, reluctance to report negative data, and incompatibility of forms and work content. (MS)
