Aim: Assessing educational outcomes in high-risk populations is crucial for defining long-term outcomes. As standardized tests are costly and time-consuming, we assessed the use of the Teacher Academic Attainment Scale (TAAS) as an outcome measure. Method: Three hundred and forty three children in mainstream schools aged 10 to 11 years (144 males, 199 females; 190 extremely preterm and 153 term; mean age 10y 9mo, SD 5.5 mo, range 9y 8mo-12y 3mo) were assessed using the reading and mathematics scales of the criterion standard Wechsler Individual Achievement Test, 2nd (UK) edition (WIAT-II). Class teachers completed the TAAS, a seven-item questionnaire for assessing academic attainment. The TAAS was also completed at 6 years of age for 266 children. Results: Cronbach's alpha 0.95 indicated excellent internal consistency, and the correlation between TAAS scores at 6 and 11 years indicated good test-retest reliability (r = 0.77, p less than 0.001). Significantly higher TAAS scores for term vs preterm children demonstrated discriminative validity. TAAS scores at 6 and 11 years were significantly correlated with WIAT-II reading (r = 0.69 and 0.75, p less than 0.001) and mathematics (r = 0.75 and 0.82, p less than 0.001) scores, demonstrating good predictive and concurrent validity respectively. TAAS scores of less than 2.5 were good predictors of learning difficulties. Interpretation: The TAAS is a brief, psychometrically sound teacher-report of academic attainment that yields continuous and categorical outcomes. It provides a cost- and time-efficient outcome measure for large-scale studies.
