This study aims to verify the validity of instructional effectiveness scale for golf players. In order to conduct this, an investigation of the scale structure and the confirmation process were verified with the evidence of customized instructional effectiveness scale based on the previous study targeted for golf players. Afterwards, study subject which was set through the data of 624 golf players were investigated by analyzing the level of difficulty, suitability, and the question response category. The following conclusions were drawn from the investigation. For the scale which consists of 21 questions under 3 factors(sporting life (5), recognized performance (9), recognized leadership (7)), 2 questions related to the recognized leadership were deleted through exploratory factor analysis, and it was found that the structure suitability was valid through the confirmatory factor analysis. However, it was confirmed that 1 question (no. 6) related to the recognized performance and 1 question (n. 16) related to the recognized leadership were not suitable, but in the response categories for the 5 point scale they were within the categories. In conclusion, it was identified that instructional effectiveness scale with 17 questions under 3 factors(sporting life (5), recognized performance (8), and recognized leadership (4)) is a valid scale for golf players. This conclusion can lead to understanding the degree of instructional effectiveness or generalizing the compared information by applying the scale identified in this study based on the golf players. Furthermore. it was concluded that this can be used as a basic material to develop a program which enhances the instructional effectiveness of golf players.
