The Teacher Compensation Survey (TCS) was a research and development effort by the National Center for Education Statistics (NCES) to explore the possibility of developing an administrative records survey that would compile compensation and demographic data on all public school teachers in the nation. A pilot survey in 2007 collected data from seven states for school year (SY) 2005-06. The number of participating states increased in subsequent years, and by 2012, data were collected from 24 states for the 2010-11 school year. TCS was discontinued after the 2010-11 collection due to budget constraints. This report summarizes the results of the data collected for the 2007-08, 2008-09 and 2009-10 school years. Limited resources prevented a more timely release of these data. While the data may be old, this report is being issued now because TCS afforded valuable lessons that are applicable to any similar, future collection efforts by NCES or by others seeking to gain a better understanding of issues related to teacher compensation. The purpose of this report is to describe both the potential of the collection and the practical problems encountered in the hopes that this will inform future survey efforts. In addition to any analytical value it may have, the TCS effort provides valuable lessons in collecting teacher compensation data. The analysis in section 3 looks closely at the problems encountered over three years of collecting TCS data and suggests ways these could be addressed.
