Test equating requires collecting data to link the scores from different forms of a test. Problems arise when equating samples are not equivalent and the test forms to be linked share no common items by which to measure or adjust for the group nonequivalence. Using data from five operational test forms, we created five pairs of research forms for…

In test-centered standard-setting methods, borderline performance can be represented by many different profiles of strengths and weaknesses. As a result, asking panelists to estimate item or test performance for a hypothetical group study of borderline examinees, or a typical borderline examinee, may be an extremely difficult task and one that can…

A common belief is that the Bookmark method is a cognitively simpler standard-setting method than the modified Angoff method. However, a limited amount of research has investigated panelist's ability to perform well the Bookmark method, and whether some of the challenges panelists face with the Angoff method may also be present in the Bookmark…

The term measurement disturbance has been used to describe systematic conditions that affect a measurement process, resulting in a compromised interpretation of person or item estimates. Measurement disturbances have been discussed in relation to systematic response patterns associated with items and persons, such as start-up, plodding, boredom,…

Making causal inferences from a quasi-experiment is difficult. Sensitivity analysis approaches to address hidden selection bias thus have gained popularity. This study serves as an introduction to a simple but practical form of sensitivity analysis using Monte Carlo simulation procedures. We examine estimated treatment effects for a school-based…

Traditional methods for examining differential item functioning (DIF) in polytomously scored test items yield a single item-level index of DIF and thus provide no information concerning which score levels are implicated in the DIF effect. To address this limitation of DIF methodology, the framework of differential step functioning (DSF) has…

Two major problems related to the identification of learning disabilities with individually administered achievement tests are discussed: (1) the appropriateness of standard versus developmental scores for determining the severity of discrepancy; and (2) the limitations of existing developmental score scales. Characteristics of the developmental…

Misreadings of pencil answer marks on test answer sheets by optical scanners cause scoring errors. Twenty-six different pencils were tested for readability differences when optically scanned. Complete light and dark marks scanned perfectly for 18 pencils. Totals for all six mark types ranged from 947 to 1726 out of 1800. (BS)

A Friends for Education (FFE) survey revealed that no state is below the norm at the elementary school level on six nationally normed commercially available achievement tests. Tests use a norm group from the past for comparison, but FFE suspects that inaccurate initial norms and teaching the test may cause high scores. (SLD)

This article discusses the validity issue in teacher-made tests. Seventh-grade students' comments about their responses to a test designed to illustrate faulty items suggests students are quite proficient in using secondary clues to figure out correct answers. Teacher comments suggest teachers are unaware they provide such clues. (Author/JAZ)

A sample (N=37) of currently published achievement tests was surveyed as to the availability of five types of technical data: (1) item selection techniques; (2) standardization; (3) types of norms; (4) types of validating data; and (5) types of reliability data. Recommendations for publishers and cautions for test users are given. (BS)

Elementary and secondary teachers (N=323) were surveyed to determine teacher use of post hoc classroom test statistics and the relationship of inservice practices to background and instructional characteristics. Results indicate teachers do not analyze test results by methods prescribed by measurement specialists. Implications for preservice…

Results of a 1987 report indicating that elementary students of all states were above the national average are assessed. Issues addressed include teaching for standardized tests, the effect of teaching on national norms, and alternatives available to protect the integrity of instruction and the validity of normed test scores.

Practices identified by experts as critical variables in eliciting writing samples were checked against 12 randomly selected studies using holistic ratings to derive descriptions of inferential statistical results for described samples. The studies often lacked precise information about these variables, limiting understanding of writing evaluation…

Results of a 1987 report--indicating that elementary students of all 50 states were above the national average--were assessed via 2 national mail and telephone surveys. Although results of data for 35 states support the general findings of the 1987 report, it appears that more specific results are less sensational. (TJH)
