Honesty is the best policy. There are resources available to Christian school leaders that will help them verify claims in areas where common knowledge is relatively limited, for example, faculty qualifications and effectiveness and quality of academic programs. To claim excellence in any of these areas, someone should first verify the facts, especially facts announced at a public gathering or stated in writing and distributed to parents or the general public. A Christian school, if it is to maintain a credible reputation for excellence, must employ the services of teachers and administrators who are academically qualified to fulfill their teaching and administrative duties. This is a fact, not an opinion.
Professional training is a prerequisite to quality teaching.
Classroom teachers should have bona fide college degrees, preferably in education. Qualified teachers are the most important component of a school, not the buildings or even the curriculums. Good schools and quality education can be achieved without the best of facilities or the best of curriculums, as long as good teachers are doing the teaching. Those trained in secular educational environments, or who did not major in education, or who are lacking in course knowledge, e.g., math, science, English, Bible, etc., greatly benefit from staff development programs. This would include in-service training, summer school classes, night classes, conventions, and seminars.
