What is NOT a requirement for licensure by endorsement in I/O psychology?

Licensure by endorsement in Industrial/Organizational (I/O) psychology typically involves several requirements to ensure that the candidate meets professional standards and ethical practices. Among these, the requirement for a passing score on the GRE is generally not necessary for endorsement. Unlike initial licensure processes that may require standardized testing to assess foundational knowledge, endorsement is primarily focused on verifying the qualifications and experience accumulated after initial licensure.

The reasons for the presence of the other requirements emphasize the candidate's professional experience and ethical standing. Having five years of practice ensures that the individual has sufficient direct experience in the field, while the submission of three professional references serves to validate the applicant's character and competence through peer evaluation. Additionally, passing a written exam on jurisprudence tests the candidate's understanding of laws and regulations governing practice, which is critical for maintaining the integrity of the profession.

In summary, while the other options reflect essential qualifications for maintaining professional standards, the GRE does not factor into the licensure by endorsement process in I/O psychology, making it the correct choice.
