The problem with which this investigation is concerned is that of determining the extent to which the elementary schools in the province of Sukhothai, Thailand, reflect an open or closed organizational climate. This study has two purposes. The first is to identify the organizational climate of elementary schools in the province of Sukhothai, Thailand, as measured by the Organizational Climate Description Questionnaire (OCDQ). The second is to determine the differences between the organizational climate of elementary schools with enrollments of 300 students or less and elementary schools with enrollments of more than 300 students. The conclusions of the study indicated that the climate of the elementary schools in the province of Sukhothai, Thailand tended to be more closed than open. Principals tend to perceive the climate of the school to be more open than do the teachers. Teachers in elementary schools with enrollments of 300 or less perceived the climate of the schools to be more open than do teachers in elementary schools with enrollments of more than 300 students. And when the school size increases the climate is more likely to be closed.

This study investigated the relationship of Executive Professional Leadership of principals in the elementary schools of Texas with specific factors which influence the quality of instruction. The primary purpose was to determine the significance to which the level of Executive Professional Leadership correlates with teacher morale, teacher performance, school organizational climate, and selected personal attributes of the elementary school principal.

Also, this study concluded that (1) experience in elementary teaching, (2) level of self-assessment as an educational leader, (3) internalization of the professional leadership definition, and (4) importance of routine administrative functions have no bearing on the elementary school principal's effectiveness in motivating his staff and improving its standards and performance in teaching.
