This bulletin provides a general description of Alberta's Grade 6 Science Achievement Test which was taken in June 1986. Discussed in this document are: (1) the purpose of the testing program; (2) the nature of the program; (3) students tested (addressing concerns related to exceptions and instruction); (4) administrative regulations; (5)…

The development and use of item shells in the construction of a series of standardized tests of reading comprehension at the elementary school level are described. An item shell is an item that is devoid of specific content, but contains key words and a distinctive syntactic structure. The specific content of the item shell varies depending on the…

The effects of using item response theory (IRT) ability estimates based on customized tests formed by selecting areas from a nationally standardized achievement test were examined. For some populations, in some conditions, IRT ability estimates can be equivalent to scores based on full-length tests. (SLD)

Standardized achievement tests and instructional accomplishment inventories involve different methodologies and cannot be equated by using conventional psychometric methods. Instructional accomplishment inventories are descriptive, and are designed to reflect the scope, sequence, and skills and emphasis in a particular instructional program.…

Passages used in the Illinois Goal Assessment Program (IGAP) reading test are intact pieces of literature, stories, and essays that match classroom reading assignments and typical student reading experiences. There are 15 testlets, each containing 5 items, associated with each passage. Each testlet requires students to demonstrate various levels…

Three different differential item functioning (DIF) detection methods were used to examine the extent to which items in a mathematics performance assessment functioned differently for matched gender groups from a sample of 1,782 sixth and seventh graders. Implications of the finding that two items were potentially biased are discussed. (SLD)

The possibility that certain features of items on a reading comprehension test may lead to biased estimates of the reading achievement of particular subgroups of students was investigated. Item response data on the reading comprehension section of a frequently used achievement test were obtained from the Anchor Test Study data files. Eight…

The validity of the assumptions under which the ordinal true score test theory was derived was examined using (1) simulation based on classical test theory; (2) a long empirical test with data from 321 sixth graders; and (3) an extensive simulation with 480 datasets based on the 3-parameter model. (SLD)

The design and development of a test of inference ability in reading comprehension for grades 6, 7, and 8 (the Phillips-Patterson Test of Inference Ability in Reading Comprehension) are described. After development of a contemporary theoretical framework for the test of inference ability in reading comprehension, the design, item development, and…

The process of constructing a test to assess geographic knowledge and understandings of fifth and sixth grade pupils is discussed. In addition, a draft of a test to measure geography skills and knowledge of physical and human geography is presented. The document is presented in three sections. In section I, information is presented on test…

Academic risk taking--the selection of schoollike tasks ranging in difficulty and probability of success--was examined for 602 students in grades 4, 6, and 8 in Taiwan. Results of a self-report measure of tolerance for failure and a risk-taking task are discussed concerning self-enhancement versus self-assessment goals, metacognitive skills, and…
