Note. n = 1,421. TAKS = Texas Assessment of Knowledge and Skills; GRADE Passage Comp = Group Reading Assessment and Diagnostic Evaluation Passage Comprehension Subtest Prorated Standard Score; WJ III Passage Comprehension = Woodcock Johnson III Passage Comprehension Subtest Standard Score; TOSREC = Test of Silent Reading Efficiency and Comprehension; ORF CBM-PF = Oral Reading Fluency Curriculum Based Measure–Passage Fluency; TOWRE = Test of Word Reading Efficiency Sight Word Efficiency Subtest; ORF CBM-WF = Oral Reading Fluency Curriculum Based Measure–Word Fluency; TOSCRF = Test of Silent Contextual Reading Fluency Standard Score; AIMSweb Maze = AIMSweb Maze Curriculum-Based Measure.

Correlation of TOSREC with measure of reading comprehension is greater than that of the comparison measure.

Correlation of ORF CBM-PF with measure of reading comprehension is greater than that of the comparison measure.

Correlation of TOSCRF with measure of reading comprehension is greater than that of the comparison measure.
