The Early Reading Assessment (ERA) is an easily administered norm-referenced screening test designed to identify those young children who have reading problems. It has high reliability, is empirically validated, and was normed on a representative sample of 1,001 children from 8 states.
Classroom teachers, special educators, speech pathologists, and school psychologists can easily administer and score the ERA subtests. Three of these are core subtests, the results of which are combined to create the Early Reading Index (ERI); the other 2 are supplemental subtests.
Core Subtests and Composite IndexThe three core subtests measure print competence pertaining to the alphabet, word identification, and word comprehension using both silent and oral formats. The content of these subtests measure both early manifestations of real reading and requisite skills that lead directly to real reading.
Supplemental SubtestsThe supplemental oral language subtests measure important non-print correlates of reading.
Scores AvailableThe ERA yields age equivalents, percentile ranks, scaled scores, and a composite, the Early Reading Index. Subtest standard scores have a mean of 10 and a standard deviation of 3. The Index has a mean of 100 and a standard deviation of 15.
Statistical Characteristics The ERA scores satisfy the most demanding standards of reliability. The reliability coefficients for all the subtests exceed .80. The reliability for the index is .94, indicating near perfect reliability. ERA scores are equally reliable for all major demographic subgroups investigated. The scores for the ERA core subtests (i.e., WWV, RON, and SOE) demonstrated large to very large correlations to 5 criterion reading scores (TOPEL, TERA-3, WJ III, TOSWRF, and TOSREC). Evidence is presented to show that the ERA Early Reading Index score can be used effectively to screen for poor readers. The results from a binary classification analysis showed a sensitivity index of .81 and a specificity index of .83; only 5 false positives were identified. The value of .92 reported for the ROC curve is considered excellent.
