Just found this at the Pearson website:

"Cancellation of Scores Due to Questionable Score Gain
If an examinees scores seem questionable when compared to PCAT scores obtained by the examinee during the previous 13-month period, the scores may be canceled. When scores are canceled for this reason, no scores will be reported to the examinee or to any score recipient schools.
Pearson follows a strict policy in determining when a score gain is questionable and thus invalid. The following explanation of this policy refers to scaled-score points, which are reported on the personal Score Report and the Official Transcripts.
If the Composite scaled score and percentile rank earned on the test date in question are 50 or more points greater than the most recent Composite scores earned within the previous 13 months, an invalidation automatically occurs (including the Writing scores) due to the large score gain.
The examinee is notified that his or her scores have been invalidated and that the scores will not be reported.
If the examinee feels that the score gain of 50 or more Composite scaled score and percentile rank points was achieved through legitimate effort, the examinee must contact PCAT Customer Relations within 60 days of the last PCAT test date to submit an appeal (via mail or fax) and documentation as evidence to support the legitimacy of the score gain (a receipt for a PCAT prep course or study materials, a letter from a tutor, etc.). The documentation will be reviewed, and the examinee will be notified regarding the outcome of the appeal within 30 days of the time the appeal is received by Pearson. If the appeal is accepted, Pearson will release the Score Gain test scores. If the appeal is denied, the examinee may be allowed to
retake the PCAT after paying the appropriate fees."
I feel sorry for people who are invalidated and are legit, as it's bound to happen with that kind of policy.
