I am a Syracuse alum, and now teach at JMU. Congratulations on your son’s acceptance to JMU!
JMU has launched a new transfer equivilency page, where it is possible to check what courses will transfer to JMU, and for what they will count. https://www.jmu.edu/registrar/students/transfer_credit.shtml
Courses will continue to be added, so just because it is not there does not mean credit will not be offered. It probably just means that no one has tried to trasfer it in the past, so it is not yet in the system.
Is the Syracuse class PAF 101 AN INTRODUCTION TO THE ANALYSIS OF PUBLIC POLICY? If so, it looks like it counts for PPA 200 INTRODUCTION TO PUBLIC POLICY.
If so, it looks like the class counts for the Public Policy Adminstration major and minor, or as a general elective. It may count for other majors or minors, as well.
