With a view to support instruction, formative and summative assessment and to provide model handwriting performance for students to compare their own performance, a Malayalam handwriting scale is developed. Data from 2640 school students belonging to Malappuram, Palakkad and Kozhikode districts, sampled by taking 240 students per each grade (grades 2 through 9) were used. The scale with 19 quality levels is formulated based on 10 point criteria viz., Shape of the letter, Size of the letter, Space between the letters, Space between the words, Space between the lines, Proportion, Margin, Slanting, Clarity and speed, and Straightness of lines. Reliability and validity of the scale were verified by ensuring the scaled handwritten scripts being identified by five experts as belonging to a particular scale value. grade norms in terms of cumulative percentage of students is provided. Students, teachers, school counsellors and parents will find the scale useful for improving Malayalam handwriting performance of learners at all grade levels in schools.
