The research reported on in this article was motivated by the absence of modifications to "A model for the study of classroom teaching" proposed by Dunkin and Biddle in 1974. In this paper we aim to provide revision input to "A model for the study of classroom teaching" by adding management capability to the group of school community context. The research examined the suitability of structural equation modelling between managerial capability and the quality of economic and accounting education based on the data, as well as the effect of managerial capability on the quality of economic and accounting education. The research instrument consisted of two inventory sets that were valid and reliable. The validity and reliability of items were tested using Cronbach's Alpha (Alpha Cronbach's = 0.89 and 0.87; R = 0.78 and R = 0.82). Data was collected from 150 principals and 150 economics and accounting teachers. Based on the analysis using the linear structural relations (LISREL) 8.80 version, the results of the study show that: (1) the structural equation model of managerial capability, including managing schools and performing management functions, managing human resources and educational personnel, and managing the learning process, can be used to estimate, predict, or explain the quality of economic and accounting education; (2) managerial capability has a significant effect on the quality of economic and accounting education in schools. Based on these findings, management capability can be included as a revision of "A model for the study of classroom teaching."
