The percentage of enrollment in physics (PEP) at the secondary level in the United States has been approximately 20% for the past few decades. In an attempt to isolate variables related to physics enrollment. Bryant (1977) conducted a path analysis model of secondary physics enrollment in New York State. This present study is a replication and extension of the study conducted by Bryant. Current data were used to verify the Bryant model and construct models with data available since Bryant's work. Data gathered by the New York State Education Department for the 1990-1991 school year were used. The source of this data included surveys completed by teachers and administrators on student characteristics and school facilities. A data analysis similar to Bryant's was conducted to determine whether the relationships between a set of predictor variables and physics enrollment had changed in the past 20 years. The findings indicate that there has been no change in the set of variables related to physics enrollment.
