Background:

The letter-cancellation task is a valuable tool for assessing psychomotor performance.
Establishing normative data is crucial for accurate clinical interpretation.

Purpose of the Study:

To establish norms for the letter-cancellation task, specifically the Selective Letter Cancellation Test (SLCT).
To provide a basis for wider clinical application of the SLCT in India.

Main Methods:

A cohort of 819 school students aged 9–16 years participated.
Participants were assessed once using the letter-cancellation task (SLCT).

Main Results:

Performance on the SLCT was significantly influenced by both age and sex.
Correction scores were developed to account for these demographic factors.

Conclusions:

The study successfully established Indian normative data for the SLCT.
These norms will enhance the test's utility in clinical settings for psychomotor assessment.
