This pamphlet discusses the need for reliable standardized tests for the selection and classification of Welsh-dominant students in Wales and for the evaluation of their language skills. Because of the correlation in performance, the standardized word-recognition test described here applies to predominantly Welsh-background individuals and not to populations with intermediate degrees of bilingual background. Specifically discussed are: (1) the foundations of reading ability, (2) standardizing the test, (3) the population sample to be tested, (4) the uses of the test, (5) test reliability, (6) test administration procedures and (7) the calculation of reading age. A sample test and sample scoring sheet are provided. (CLK)
