What is the test for establishing a prima facie case of wrongful termination?

We assume without deciding that the District's nonrenewal amounted to a termination and that Marshak established a prima facie case of wrongful termination. See Washington v. Garrett, 10 F.3d 1421, 1433-34 (9th Cir.1994) (prima facie case requires plaintiff to show (1) membership in a protected class, (2) that he was qualified for the job, (3) an employment decision, and (4) that the position was given to a nonprotected class applicant with equal or inferior qualifications).
