The summary report, a condensed version of the final report of the Thai-Alberta Cooperative Assessment Project, is drawn largely from Chapter 8 of the final report and presents the essential nature, scope, and findings of a project involving data from over 5,000 Thai participants (principals, teachers, students, parents and alumni) in a sample of 16 rural secondary schools (RSS) in all parts of Thailand. The summary contains an introduction; background of the RSS project; rationale, objectives and design of the assessment; findings concerning specific and general objectives; a "global conclusion"; recommendations concerning RSS schools and the conducting of a cooperative assessment; and appendices of selected tables. The report concludes that the RSS project, a massive and complex innovation in rural and district secondary schools in Thailand, has demonstrated the possibility of greatly improving secondary education in the rural areas of Thailand and that such schools could be brought into the project throughout Thailand, provided adjustments are made to the educational system to offset the selective character of the RSS schools, a phenomenon which has emerged as a result of the success of the schools. The executive summary is a condensed version of the summary report and final report and follows the same organization. (AN)
