N2 - Rating scales and the extent to which raters use them effectively are two important factors that influence scoring validity of language tests when open-ended writing tasks are concerned. Research regarding rating scale development and validation in the assessment of English is ample; however, there has been no research on scale validation in the assessment of Turkish as a Second Language (TSL) to this date. This study reports on the development of two analytical rating scales used to assess academic writing skills of test takers in TSL, and presents quantitative evidence on the rating scale validation. For this purpose, texts written by 39 TSL students were scored by three raters. The analyses were conducted using Many-facet Rasch Measurement. Results indicate that empirically-developed analytical rating scales were used consistently and appropriately by the raters providing evidence for the reliability and effectiveness of the rating scales.
