The main aim of the pilot project is to establish inter-rater reliability, internal variability and variability of results got in two different ways of the Nine Hole Peg Test, Purdue Pegboard Test and Box and Block Test administered according to the new Czech extended versions of their manuals.

New Czech manuals for the Nine Hole Peg Test, Purdue Pegboard Test and Box and Block Test were made by back-translation method. They were updated and extended by new rules for unification of their performing. The manuals include instructions for performing three trials of each subtest.

At least 30 occupational therapy students will be tested by those three tests according to those new Czech manuals. Video of students' performance will be obtained.

The inter-rater reliability, internal variability and variability of results got in two different ways will be established.
