About 500,000 students took the SAT college-admissions test last October. The College Board, which owns the test, says about 5,000 of them received wrong scores.
    The problem became known after 2 students questioned their scores. They asked to have their tests scored again, this time by hand instead of by computer. Further investigation led to more and more wrongly scored tests. Most of the scores were too low.
    College Board spokesman Brian O’Reilly says only four students gained 300 points or more. He says most gained 90 points or less. A perfect SAT score is 2,400 points.
    The College Board is not telling students or colleges about scores that were too high.[33]Mr. O’Reilly says students should not be punished for something out of their control.
    He says the scores were no more than 50 points too high. He tells us correcting them would not have affected college acceptance decisions.
    The tests went to a processing center in Texas. Pearson Educational Measurement has scored the SAT for the College Board since March of last year.
    The College Board says[34]humidity in the air caused the paper to expand and change the position of the answers. It says the problem affected tests with light or incomplete answer marks.
    Mr. O’Reilly says Pearson has already corrected the problem. He says the company has improved its computer systems and will now scan all answers two times.
    The College Board has asked schools to reconsider any students they rejected before their SAT scores were increased. Higher education officials say acceptance decisions are based only partly on test scores, but[35]higher scores can mean more financial aid.
