the average score on the 4th grade math tahs test(2011) was 609.15 with a standard deviation of 90.91. how can I find out if the class averge is less than the schools average.

You take the scores of each student in the class, add them up, and then divide by the number of students. If that number is less than 609.15 then the class average is less than the school average.
