Johanna earned a doctoral degree in developmental psychology and supplemented her coursework. What must be done for her to sit for the licensing examination?

To sit for the licensing examination, Johanna must provide certification from the program director at an APA-approved school. This requirement ensures that her doctoral degree in developmental psychology meets the necessary academic standards and educational qualifications established by the relevant licensing authority. The program director's certification serves as a verification of her requisite training, competencies, and adherence to the prescribed psychological education standards.

This step is crucial because it affirms that the candidate has completed an adequate level of professional preparation in psychology, which is a prerequisite for the licensing process. Without this certification, her eligibility to take the examination would be uncertain, regardless of her earned degree or coursework.

The other potential choices do not correctly address the requirements for sitting for the licensing exam within the context of developmental psychology in Pennsylvania. The necessity of completing a second degree or undergoing a review by the National Register are not standard prerequisites for licensure, reinforcing that the certification from an APA-approved program director is the appropriate pathway for Johanna.
