This exploratory study on the College Board's Admissions Testing Program (ATP) Physics Test can be divided into two main parts, each designed to address a specific set of questions: Part I, Are there any systematic differences in male/female performance on individual items or subgroups of items that can help in interpreting the differences between males and females in overall performance on the test?, and Part II, Are there any factors that, when related to performance data on individual items or subgroups of items, can help in interpreting the overall performance differences and perhaps provide insights into unique characteristics of the female physics student? Questions from Part I are addressed by performing a standard test analysis following procedures associated with classical test theory. The second part of the investigation requires considering the available ATP data in the context of what is known from more general research of theories. (Author/GK)
