Students' learning math difficulties are influenced by various factors, both internal factors (themselves) and external factors (from outside the students themselves). One of the external factors that can affect student achievement is the campus facilities and infrastructure where they study. This paper aims to estimate structural equation models, which can represent the relationship between latent variables, and the relationship between latent and indicator variables. Besides, it is also to determine which construct has the most influence on the achievement of four indicators, which include: Campus Environment (KPS), Family Environment (LK), Community Environment (LM), and Seating (TD) towards Self (DS). The research data was obtained through a survey using a questionnaire to Universitas Padjadjaran students in the Mathematics Study Program. Data were measured using a Likert scale and using a simple random sampling technique. Data analysis was performed using Structural Equation Modelling (SEM). The results of the data analysis show that the parameter estimators of the four indicators are 0.29, 0.34, 0.14, and 0.12 respectively, with the R-squared coefficient of determination of 0.90. So that SEM is an analysis that can provide information that is used to support the learning process policymaking.
