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.

The problem of this study was to determine the pupil control ideology—conceptualized as a continuum from custodialism to humanism—of principals and teachers in public elementary schools in the province of Sukhothai, Thailand. The instrument, the Pupil Control Ideology Form (PCI Form), consists of twenty likert-type items. Responses to each statement are indicated on a five-point scale, ranging from "strongly agree" (five points) to "strongly disagree" (one point). Scores derived from the PCI Form were used as indicators of respondents' orientation toward the control of pupils in elementary schools of Sukhothai, Thailand. The reliability coefficient of the PCI Form yielded a Pearson Product Moment Coefficient of .91 and .95 when using the Spearman-Brown formula. The instrument (PCI Form) was translated into Thai, validated by six judges who were selected on the basis of their positions and knowledge of Thai education. The reliability of the revised questionnaire was determined by a pilot study (test-retest technique) which involved twentyteachers and ten principals of public schools in Sukhothai, Thailand. The results of the Pearson Product Moment Coefficient gave the correlation of .87 and .93 using the Spearman-Brown formula.
