In 1985, in response to both first- and second-wave reform reports criticizing the nation's schools for a lack of rigor in their instructional programs, the achievement formula research project, "Techniques of Responsive Intervention to Validate Effective Teaching" (TRIVET), was developed. Between 1985 and 1988, the project was piloted in three northeastern Ohio school districts and involved 168 students. During the 1988-89 academic year, it was further piloted in the Cleveland Public School District, where it involved 1,460 students. The operation of this formula enables districts to formatively monitor, summatively evaluate, and reliably predict student achievement levels as the most significant outcome of the reform effort. As an administrative training project, TRIVET has been designed to provide the building principal or other instructional leader with the necessary knowledge, processes, and skills to more effectively diagnose classroom teaching. The TRIVET program, divided into eight separate modules of instruction based on teacher effectiveness research, was designed to occur during 72 clock hours of instructional time. Each module consists of direct instruction, application with actual teaching segments, and feedback by instructors. Participation in the achievement formula project demonstrates a philosophy that student achievement is the responsibility of the entire district and the principal objective of its collective resources.
