The work carried out in Edmonton School District Number 7 as part of the Educational Quality Indicators (EQI) project in the Alberta (Canada) schools resulted in development and validation of processes, criteria, and reporting methods related to student achievement in six "essential learning outcomes" keyed to the more traditional Alberta Education subject-based curriculum. The approach was based on the concept of common "tasks" performed by students at different levels of years of schooling and the assessment component was predicated on the principle that teachers' informed judgments about student performance are valid and reliable. This report describes the processes used, the principles and definitions to which all participants adhered, student growth results over 3 years, and implications. Samples of teacher documentation, performance criteria lists, prototype student tasks, and examples of student work are appended. Also examined were the role and potential of computer technology in recording, analyzing, and presenting student growth. Samples of prototype user screens are included. Assessment development in the district remains a work in progress, as the report attests. Eight tables and eight figures present study findings. (Contains 27 references.) (SLD)
