I ran across this article in Wikipedia and thought I’d comment on it.
What is the Brigham Young University Testing center?
A center at BYU for the sole purpose of administering tests to students.
Good things about this type of center:

• Valueable class time is not wasted on a test. The professor doesn’t have to schedule lectured around test scheduling and therefore can continue with the course of study
• Students have plenty of time to take a test. Many times I have had to rush to get done with a test by the time the allotted time is up. There is no time pressure to take a test

Negative things about this type of center:

• Potential for long lines (as the article describes). However there is a web cam available for those who’d like to see how long the line is before taking their test.
• Neutral environment. Many people tend to achieve higher scores on tests when they take it in the room which they learned the material. It was not uncommon during my college experience to visit the classroom afterhours to try to review new material. Sometimes you tend to associate items in the room with items which are on the tests. Having a testing center is somewhat of a neutral environment, which might mean students have increased potential to score lower than in the environment in which they learned the material. However this neutral environment might help measure how well the student has learned the material, and can recite it in any environment.
  There is also a slight potential for a student to have a bad experience in the testing center and therefore associate the center with failure. This of course is merely a psycholocial concern and cannot be alleviated unless the student gains control of their fears themselves.

I think a testing center could potentially be a good idea. I would have liked to have had the option at Lipscomb.
