AbstractMultiple‐regression procedures were used to assess the effectiveness of the ABC Inventory and the Metropolitan Readiness Test (MRT) in predicting first and third‐grade reading achievement. Sex and chronological age were included in the first‐grade analysis (N= 62) and the first‐grade PMA intelligence test score was added to the equation in predicting third‐grade reading (N= 65). MRT performance accounted for 11% of the variance in first‐grade SRA reading scores (R= .34). In predicting third‐grade reading, the MRT accounted for 26% of the variance and the PMA IQ scores accounted for an additional 6% (final multipleR= .57). No other predictor made a significant contribution to explaining variance in first or third‐grade read
