Hire college professors to aid in the scoring process as readers.
Develop a standard of scoring for the free-response portion of the test. This is done by gathering with official readers, discussing guidelines and scoring a few random tests collectively.
Scan the multiple choice section of the test through the computer according to the College Board guidelines.
Assign the free-response written section to one of the college professors appointed by the College Board to be a reader. These readings take place over 2 weeks at the beginning of June.
Convert the final score of the test to the 5-point AP scale by equating the results of this year's test with the results of a past test. This is done by comparing the scores for all tests taken this year in one question set to the scores from an identical question set in a previous year's tests.
