A private religious school is hiring a new teacher for its world history class. The school's administration has a policy of only hiring teachers who are active members of its specific faith, regardless of the subject they teach. An applicant who is highly qualified to teach history but does not belong to the school's faith is rejected solely on this basis. Analyze this hiring decision. Is the school's policy likely to be considered a legally permissible exception to the general rules against employment discrimination? Explain your reasoning.
