Ralph has just taken two achievement tests. He scored at the 90th percentile on the Ohio Reading Test (ORT). He scored at the 50th percentile on the California Mathematics Inventory (CMI). Can we conclude that Ralph has higher achievement in reading than in mathematics?
 
  a. Yes, because a percentile score of 90 is well above average, whereas a percentile score of 50 is only average.
  b. Yes, provided that both tests have been shown to have content validity for the curriculum at Ralph's school.
  c. No, because the two percentile scores are both essentially average scores.
  d. No, because the norm groups for the two tests are probably different.

Question 2

When choosing a standardized achievement test to administer in your own school, three of the following are important considerations. Which one is least likely to be of concern?
 
  a. Does the test reflect the curriculum at your school?
  b. Is the norm group similar to the students at your school?
  c. Have the items been written by people with classroom teaching experience?
  d. Does the test manual provide clear directions for administering the test?
