+# New Jersey CCAP activity eligibility tests
+# Per N.J.A.C. 10:15-5.2, each head/spouse in the CCAP unit must
+# independently qualify (work hours above the weekly threshold or
+# full-time study) unless the family is otherwise covered by a
+# CCDF-recognized fallback activity (TANF, CP&P, etc.).
+#
+# The test also must not vacuously pass for an SPM unit that contains
+# no head/spouse (e.g. an unaccompanied-minor unit): activity eligibility
+# requires at least one head/spouse in the unit.
