DoctrineEducational systems and school directors create, from time to time, various methods to evaluate the teacher, be it grade school or university. The methods vary, depending on the pedagogical philosophy.

By pointing out such things to the brothers and sisters, you will be a good servant of Christ Jesus, having nourished yourself on the words of the faith and of the good teaching that you have followed.
1 Timothy 4:6 NET

To be a good servant of Christ means speaking what people need to hear, not what they want to hear. It means teaching sound doctrine, not giving in to popular false teachings.

When used to refer to a teacher, the adjective “good” transmits the idea that he does his work well in God’s sight. The teacher is good when he faithfully delivers the divine teaching, not when he impresses or pleases his hearers.

This evaluation method will never change.
