I remember in college, filling out those course evaluations - it seemed that my evaluation of the course was always different at the end (after the exam) than it was at any point during the actual course. Now one can make an argument that once the class is over, one can see the whole picture, and evaluate fairly... but one could also say that in the let down from the stress of the exam produced more favorable evaluations for the professor.
Now luckily for me, I'm not in the education-as-comodity business, and I don't have to set these policies; but I think I've noticed a trend. When I took a job a few years back at Harvard University Facilities Maintenance, I came to the job with years of experience. Not only had I been a landscape Foreman on the North Shore, but I had been the personal gardener on Two large Estates for a total of seven years, and studied pruning and arboriculture besides. I remember running into this attitude; that it doesn't matter what you know, how good you are, or even how you do your job, if you haven't been here as long as us, become as miserable as us, and become like us, you'd better step back.
I once took a position as a Correctional officer, passed the 80 hour course with the highest grade in the criminal justice academy, but when I got onto the job, I met the same attitude.
Over time I learned to expect this attitude, I was super fortunate to have a foreman at the construction company I worked for, who was also a great teacher. He understood that if you don't give young "whippersnappers" a chance, they'll just drift from job to job, until they resign themselves to misery. He seemed to delight in instilling a love for craftsmanship in the guys who worked under him, and he had a way of making us feel good about ourselves... A true master craftsman.
My point in writing this is that we seem as humans to slip into this bad attitude, that "if I had to go through hell, then you should have to go through it too." We call it initiation or hazing if it happens in the military or on a sports team. But what about if it happens in ministry? We tend to make the trials of the next generation just a little harder than our own. We feel justified in giving the professor a better rating, knowing that the class will be harder for the students who follow.
"Do not deceive yourselves. If any one of you thinks he is wise by the standards of this age, he should become a "fool" so that he may become wise. For the wisdom of this world is foolishness in God's sight. As it is written: "He catches the wise in their craftiness"; and again, "The Lord knows that the thoughts of the wise are futile." So then, no more boasting about men! All things are yours, whether Paul or Apollos or Cephas or the world or life or death or the present or the future--all are yours, and you are of Christ, and Christ is of God." (1 Corinthians 3)
"Who is wise and understanding among you? Let him show it by his good life, by deeds done in the humility that comes from wisdom. But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. Such "wisdom" does not come down from heaven but is earthly, unspiritual, of the devil. For where you have envy and selfish ambition, there you find disorder and every evil practice. But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere." (James 3)
