“…Sharpley & Edgar (1986) separated reading into two components, vocabulary and comprehension, nding correlations between teachers and student measures of 0.42-0.44 and 0.50-0.56 for vocabulary and comprehension, respectively. Such correlations have been interpreted as indicating the validity of teachers' judgements (Hoge & Coladarci, 1989;Hopkins et al, 1985;Wright & Wiese, 1988), although many have accounted for only small shared variance between teacher and test measures. However, Hoge & Coladarci (1989) suggested that this may be a consequence of indirect estimates of achievement by teachers in the form of ratings and rankings; asking teachers to estimate directly student performance scores for a particular test does appear to improve correlations to a range of 0.68-0.82 (Doherty & Conolly, 1985;Wright & Wiese, 1988;Freeman, 1993).…”
