Rapid automatized naming test in Tamil (RAN-T) is a tool which helps to assess early reading skills in Tamil- speaking children between the age range of 5-8 years. The RAN-SC (Single Category) consists of four tasks: RAN-O (Object), RAN-C (Colour), RAN-L (Letters) and RAN-D (Digits); the RAN-AC (Alternate category) consists of two tasks, RAN-DL (Digit-Letter) and RAN-CDL (Colour- Digit-Letter).

RAN-T tasks, highlights the impact of age, gender, and task category on their naming speed and accuracy.
