32:T796,md` In England, the writing of pupils at the end of their Primary phase of education is graded by teachers using the Teacher Assessment Framework [TAF](https://www.gov.uk/government/publications/teacher-assessment-frameworks-at-the-end-of-key-stage-2). Using the TAF rubric, the teachers grade students with three grades: Greater Depth Standard (GDS), Expected Standard (EXS), Working Towards Standard (WTS). The teachers consider a range of writing produced by their students and decide on a grade. To study the reliability of the TAF grading process [No More Marking](https://www.nomoremarking.com/?utm_source=blog&utm_medium=referral&utm_campaign=taf/) recruited 30 teachers experienced in using the TAF to grade a sample of 349 scripts. Despite being experienced, all teachers were required to undergo further training from a moderator with experience as a Local Authority Lead Moderator and as an Operational External Moderator and Deputy Standardisation Team Leader for the national Standards and Testing Agency. The following interactive notebook shows the scripts that were graded along with the range of grades given by the teachers. You can see details of the task and the conditions [here](https://blog.nomoremarking.com/assessing-primary-writing-2019-20-year-6-results-f1628004e7d3). In addition to the grading by the TAF, all scripts were judged using Comparative Judgement (CJ) as part of the national [Assessing Primary Writing](https://www.nomoremarking.com/?utm_source=blog&utm_medium=referral&utm_campaign=taf) project. The grade assigned by the CJ process is provided in the table. The research concludes that the CJ approach achieves twice the classification accuracy of the TAF approach, in the same amount of time.
