An evaluation of the Ferguson form boards and the derivation of new age and grade norms. Part 1: Procedure and derivation of norms

Abstract

Restandardization of the Ferguson form boards on two representative urban-commercial school populations, grades 2-8, ages 5-17, inclusive, is described. Complete revised instructions for giving the test are included. The problem of scoring is considered, and evidence is presented for using a "score," i.e., time divided by number of units (holes) correctly completed. Discussion of validity and reliability, and presentation of norms are reserved for a later article. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
