The National Center for Research on Evaluation, Standards, and Student Testing (1996) defines assessment system as follows:
"The combination of multiple assessments into a comprehensive reporting format that produces comprehensive, credible, dependable information upon which important decisions can be made about students, schools, districts, or states. An assessment system may consist of a norm-referenced or criterion-referenced assessment, an alternative assessment system, and classroom assessments."
For further information on assessment systems, refer to Principles and Indicators for Student Assessment Systems (National Forum on Assessment, 1995).
