The Assessment of Sight-word Reading and Fluency (ASWRF) is constructed on the basis of the trend of the assessment of decoding. Based on the frequency and grades, five different forms are designed to assess the different sight-word size for different graders: B1, B2, B34, B57, and B89. Each of them consists of 60 characters to ask students to read the character and make a word with the character and the accuracy of the character-recognition (CR) and fluency of CR are scored and get the result from the national norm or East-Taiwan norm. The study aims to reported the idea of the design of the ASWRF and confirm it with the reliabilities, validity, and utilities. The internal reliabilities of each form in each grade are above .90, and 2-week stable correlation coefficients are above .80. The internal validity and construct validity are reported with satisfactory evidence. The principles of assessment administrated are reported with the convincing data to support it, and the utility of the assessment in the diagnosis of the poor readers is approved from the intra-sample comparison and case study. To improve the comparison of the different forms of the ASWRF, the competence-equivalent scale is provided for follow-up studies. The recommendation of practical application and future studies are made in the end.
