Three studies involving elementary students examined methodological issues in curriculum-based reading assessment. Results indicated that (1) whereas sample duration did not affect concurrent validity, increasing duration reduced performance instability and increased performance slopes and (2) domain size was related inversely to performance slope…

This assessment of the reliability and validity of skills analysis programs within curriculum-based measurement (CBM), with various groups of handicapped and nonhandicapped youngsters, indicated that the skills analysis programs in spelling and math provided consistent information that related well to the primary graphed CBM scores. (Author/JDD)

Comparison of special education teacher (n=18) and computer-scored curriculum-based measurements (CBM) of spelling found that computer scoring accuracy was significantly higher and more stable. Additionally, high correlations were found between the CBM spelling scores and a standardized test of spelling achievement. (DB)

This literature review discusses the match between tests and curricula, measurement validity and instructional utility when sampling student performance in general and advantages/disadvantages of sampling performance in the curriculum. It concludes that sampling from the curriculum is not essential and outlines three critical features ensuring the…

The effects of aggregation on the reliability of measures of academic performance were explored in two studies. In the first study, 30 elementary-age children were tested four times on the same forms of the Woodcock Reading Mastery Tests and the Ginn 720 Reading Passage measures. Group stability coefficients, within-subject reliability…

Procedures for developing curriculum-based measurement (CBM) systems are presented as an approach to special education problem solving. CBM procedures are discussed within the context of a decision-making matrix, focusing on "what" and "how" to measure and how to use data. An example applies the method to reading-aloud…
