In this study, we examined the reliability and validity of two curriculum-based measures as indicators of performance in a content-area classroom. Participants were 58 students in a 7th-grade social studies class. CBM measures were student-and administrator-read vocabulary-matching probes. Criterion measures were knowledge pre-and posttests, the social studies subtest of the Iowa Test of Basic Skills, and student grades. Results revealed moderate alternate-form reliability for both vocabulary-matching measures. Reliability of the measures was increased by combining scores across two testing sessions. Correlations between the predictor and criterion variables were moderate to moderately strong, with the exception of those between vocabularymatching and student grades. Observed scores for students with LD were lower than for students without LD on both student-and administrator-read vocabulary-matching measures. Few differences in reliability and validity coefficients were found between the student-and administrator-read measures. Results are discussed in terms of the use of CBM as a system for monitoring performance and designing interventions for students with learning disabilities in content-area classrooms.

The technical adequacy of curriculum-based measures in the form of short and simple vocabulary-matching probes to predict students’ performance and progress in science at the secondary level was investigated. Participants were 198 seventh-grade students from 10 science classrooms. Curriculum-based measurements (CBM) were 5-min vocabulary-matching probes administered once weekly over a period of 14 weeks. Criterion measures were knowledge pre- and posttests, the science subtest of the Iowa Test of Basic Skills (ITBS), and course grades. Alternate-form reliability coefficients ranged from r = .64 to .84. Coefficients increased over time and by combining scores across probes. Correlations between scores on the vocabulary-matching and criterion measures ranged from r = .55 to .76. The estimated mean group growth rate on the vocabulary-matching measure was .63 correct matches per week, which was significantly different from zero. The measures produced significant interindividual differences in growth rates, and growth on the measures was related to performance on the ITBS, course grades, and pre–post gains on the knowledge test. Results provide initial support for the technical adequacy of vocabulary-matching as an indicator of performance and progress in science.

The purpose of this study was to examine the reliability and validity of curriculum-based measures as indicator of growth in content-area learning. Participants were 58 students in 2 seventh-grade social studies classes. CBM measures were student- and administrator-read vocabulary-matching probes. Criterion measures were performance on a knowledge test, the social studies subtest of the Iowa Test of Basic Skills (ITBS), and student grades. Both the student- and examiner-read measures reflected change in performance; however, only the student-read measure resulted in interindividual differences in growth rates. Significant relations were found between the growth rates generated by the student-read vocabulary measure and student course grades, ITBS scores, and growth on the knowledge test. These results support the validity of a vocabulary-matching measure as an indicator of student learning in the content areas. The results are discussed in terms of the use of CBM as a system for monitoring performance and evaluating interventions for students with learning disabilities in content-area classrooms.

Many students continue to experience reading difficulties into their secondary-school years. Difficulties include poor word decoding, limited vocabulary knowledge, and deficits in working memory capacity. Such difficulties limit the ability of students to acquire new knowledge and be successful in content-area classes. In this article, we describe a curriculum-based measure, vocabulary matching, that teachers can use to assess and monitor the performance of students with reading difficulties in the content areas. Vocabulary matching, has been found to be a valid and reliable measure of performance and progress in content areas. A case study is provided to illustrate the use of vocabulary matching in content-area instruction.
