The SAT is a a-hour test of both verbal and mathematical abilities which is used as part of the process 
for evaluating applicants for admission to American universities. In 1995, the College Board, which 
administers the SAT, re -centred the scoring scale for the test. It did so by re - establishing the 
original average score of 500 on the 200 -800 scale. The scale had not been adjusted since 1941, 
when it reflected the norm of some 10,000 students, frequently from public schools and applying to 
the nation's most selective universities. Over the years the average score had shifted below 500 as a 
larger number of students began taking the test, and verbal and maths scores had ceased to become 
comparable. Now the scores represent a more diverse university-bound population of about 2 million 
students.
