This is a presentation of six research reports conducted for a year-round school articulation and compatibility study. Presented are the reports of the committees concerned with a year-round school research bibliography library, a student employer survey, a general air-conditioning survey, a review of selected year-round school surveys, a summer school articulation report, and a research report of the 44-17 and other methods of year-round secondary school operation. The student employer survey was carried out in order to sample the conditions under which high school students are employed and the effect that year-round school would have on youth employment and the general business operation. The general air-conditioning survey was to determine the factors existion in the area schools; no attempt was made to estimate the operation costs for increased air-conditioning. The stress of the survey of year-round schools was placed on the most recent studies and surveys accomplished in San Diego County that attempted to measure the attitudes and opinions of various populations toward the year-round concept.
