This paper profiles the student subgroup achievement and gap trends in Iowa for 2010. In grade 8 (the only grade in which subgroup trends were analyzed by achievement level), Iowa had data for racial/ethnic subgroups, low income students, and boys and girls at the proficient and advanced levels. Trends at the proficient and advanced levels were…

The No Child Left Behind Act imposes sanctions on schools if the fraction of each of five racial groups of students demonstrating proficiency on a high stakes exam falls below a statewide pass rate. This system places pressure on school administrators to redirect educational resources from groups of students most likely to demonstrate proficiency…

This report presents elementary school test trend data for the Chicago Public Schools (CPS), Illinois for 2000 for the Iowa Tests of Basic Skills (ITBS). In spring 2000, ITBS trend data show that mathematics test scores in the CPS elementary schools continue their long-term improvements for all age levels. Positive trends in ITBS reading scores…

In a previous article, we (Naglieri & Ford, 2003) provided evidence from a large-scale study that similar proportions of White, Black, and Hispanic children would be identified as gifted using the Naglieri Nonverbal Ability Test (NNAT; Naglieri, 1997). Lohman (2005) has taken issue with our conclusions and our methods. We provide several…

Findings indicate that (1) Black children have higher self-esteem than Whites; (2) girls of both races have lower self-esteem than boys; (3) Black children from broken homes have lower self-esteem in desegregated schools; and (4) Black children in segregated schools receive higher marks, but do not do as well on national tests as do their…

Primarily a longitudinal and quantitative analysis of achievement functioning, this experiment sought to identify factors which promote or impair the learning of individual children. The 683 Junior High students were divided into one of eight groups according to sex, race and whether their seventh grade Iowa Test of Basic Skills Composite score…

The predictive validity of the California Achievement Test, Reading (CAT-R) was examined for 480 Hispanic and Anglo pupils in Grades 2 and 3. The validity of the CAT-R as a predictor for reading for combined groups of Hispanic and Anglo pupils appeared to be limited. (Author/LMO)

Examined the incidence of differential item functioning (DIF) on 3 subtests of the Iowa Tests of Basic Skills using test scores for 2,867 Alaskan students, characterized as "Native" or White at fourth and sixth grades or sixth and eighth grades. Effect size differences favoring whites were larger when students of equal English…

Student achievement as reflected in standardized test scores is not a unitary construct, but a set of interdependent components representing degrees of knowledge of various subject areas. The interdependency of achievement components imply a positive feedback process. Weaknesses in one area reinforce weaknesses in others; strengths in one area…

The average grade equivalent reading comprehension scores of students in Black schools are compared to those of students in White schools under two forms of test administration. Concludes that use of grade level testing with the Iowa Tests of Basic Skills is biased in favor of low scoring subgroups. (Author)

The beneficial effects of changing an answer on a multiple choice test were examined for elementary school students, with particular emphasis on the answer-changing behavior of minority versus non-minority groups and high-income versus low-income students. Test booklets from students in grade 2 and answer sheets from students in grades 4, 6, and 8…

The reliabilities of 6 item bias indices and correlations among them were investigated for each of the 11 tests of the Iowa Tests of Basic Skills (ITBS). The difficulty and delta indices detected group differences in relative item difficulty. Biserial and point biserial indices detected group differences in item discrimination. The Scheuneman and…

The Anchor Test Study provides a method for translating a pupil's score on any one of eight widely used standardized reading tests for Grades 4, 5, and 6 to a corresponding score of any of the other seven tests, as well as furnishing new nationally representative norms for each of the eight tests. In addition, the Study presents new estimates of…
