A Curriculum-Based Passage Reading Test for Monitoring the Performance of Low-Progress Readers: The development of the WARP

Results are presented from two studies involving 190 primary and high school (Year 7) students and 146 older low-progress readers in the late primary years. These studies contribute towards the development of five 200 word standardised passages which may be employed interchangeably to monitor the performance of low-progress readers towards achieving functional literacy. The passages are shown to possess both high parallel form reliability (0.94 to 0.96) and internal consistency (0.97 to 0.99), and also good criterion validity (0.78 to 0.80) with reading accuracy. Appropriate growth in performance over the primary years is also demonstrated. These findings suggest that an extrapolated model of curriculum-based measurement (CBM), which incorporates elements of more traditional reading assessments, would overcome some of the problems associated with CBM.
