The Conejo Valley (CA) Unified School District Educational Results Information System (ERIS), a generalized District master program assessment plan to obtain results information for decision-makers at all levels, has been developed. This plan establishes guidelines, evaluates the current status of the use of educational results information and establishes priorities for development of additional parts of the system. Important components of ERIS are: the annual test schedule; the linkage of planning and evaluation; the elements of both school and district Pupil Performance Profiles; the development of district, school and classroom pupil progress reports; and an analysis of the existing District Assessment Program. ERIS includes the following existing assessment programs: (1) California Assessment Program; (2) District Competency (Proficiency) Testing Program; (3) District Norm-Referenced Group Achievement Testing Program Comprehensive Test of Basic Skills (CTBS); (4) other norm-referenced achievement testing programs-- College Entrance Examination/ Advanced Placement Program (CEEB/APP), Preliminary Scholastic Aptitude Test (PSAT), Scholastic Aptitude Test (SAT), The California State University and College English Placement Test (EPT); (5) assessment related to the affective domain--School Attitude Measure (SAM), Substance Use Survey, Secondary Schools Guidance Needs Assessment; and (6) assessment related to the psychomotor domain--The Physical Performance Test for California (Revised).
