The problem with which this investigation is concerned is that of describing the secondary school principalship as perceived by selected principals and teachers in Bangkok, Thailand. The purposes of this study are (1) to collect selected demographic data about the secondary school principals and teachers in government and private schools, and (2) to measure and determine the relative effectiveness of principals of government and private secondary schools in Bangkok, Thailand, as perceived by secondary school principals and teachers. The conclusions of this study are as follows: (1) principals in government and private secondary schools appear equivalent in professional preparation as measured by highest degree held, (2) principals in government and private secondary schools earn equivalent salaries, (3) teachers in private secondary schools have less professional preparation than teachers in government secondary schools, (4) teachers in government schools are better paid than teachers in private schools, (5) principals in both government and private secondary schools perceived their effectiveness as higher than did the teachers in those schools.
