1988 is the eighth year of the Arizona Pupil Achievement Testing Program which is administered to fulfill the requirements of Arizona Revised Statutes Section 15-741 through Section 15-744. This legislation mandates that a nationally standardized norm-referenced achievement test be administered during April to all pupils enrolled in Arizona public schools, grades one through twelve, in the subjects of reading, grammar and mathematics. The legislation exempts the testing of specified groups of handicapped pupils. A revision of the law passed in 1982 allows the governing board of a school district to exempt pupils who are non-English monolingual or predominantly speakers of a language other than English for up to three years. For 1988, the Arizona State Board of Education adopted three different tests to fulfill this legislative mandate: the Iowa Tests of Basic Skills (ITBS) published by The Riverside Publishing Company for use in grades one through eight; the Stanford Achievement Test (SAT-7) for use in grade nine; and the Stanford Test of Academic Skills (TASK) for use in grades ten through twelve. Both SAT-7 and TASK are published by The Psychological Corporation. For Arizona, pupil scores are reported by subject, subtest and skill at the pupil and classroom levels. Scores are then aggregated to the school, district, county and state levels. A total of 502,009 Arizona pupils was tested during the period of April 4 through April 15, 1988. This is 3,778 more pupils than were tested in 1987. A total of 7,011 pupils who are non-English monolingual or predominant speakers of a language other than English was exempted from testing. This is 541 more pupils than were exempted in 1987. The statewide data reported are based on the performance of the tested pupils who were enrolled in 957 schools in 213 districts. The appendixes provide the 1988 percentile ranks for students in grades one through twelve in reading, language, and mathematics. (AA)
