Study on the Design for Two-Stage Stratified Cluster Systematic Sampling: Focusing on the Case of a Survey on the Customized Student Support

This is a case study that establishes a sample survey design plan for all grades in elementary, middle, and high schools in Korea for the purpose of representing population at the national level. The main purpose is to provide academic and practical implications for survey-based education data collection by reflecting the structure and characteristics of school data. To this end, based on cases of survey design at the national level in Korea and abroad and the results of simulation experiments to secure representativeness of the results by grade for all elementary, middle, and high schools, a two-stage stratified cluster systematic sampling scheme was derived, and a plan for obtaining results at the national level and by grade was presented, and the main issues in the process were discussed.
