Results

Effect on the District Summary

The removal of the suspect test scores had a small effect on the district summary, with a .2% drop in passing math, .3% drop in passing reading, and an overall passing .1% drop.

Effect on the School Summary

The removal of the suspect test scores had minimal effect on the School Summary once the number of students with missing test scores were removed from the analysis totals, only changing the passing percentages on one school out of fifteen, and changing all three scores (% passing math, % passing reading, and % overall passing) by less than 1% in each case. Pre removal the overall passing scores for Thomas HIgh School dropped to 65%.

Effect on:

Math and reading scores by grade - The most obvious effect is on the 9th grade scores for Thomas High School, as they have been removed from the analysis entirely.

Scores by school spending - There was little to no effect on the scores categorized by spending. Schools with lower spending per student trend to have higher overall test scores.

Scores by school size - There was little to no effect on the scroes categorized by school size. Small to Medium schools trend to have higher overall test scores.

Scores by school type - There was little to no effect on the scores categorized by type. Charter schools trend to have higher test scores than District schools.

Summary:

• Replacment of the ninth grade test scores with NaNs redued the pass percentage on math by .2%, on reading ny .3% and overall by .1%.
• It affected the School Summary on one school out of 15, changing all of the test scroes by less than 1% once the pass rate was adjusted to remove the student counts that had the grades removed.
• Removal of the grades dropped the overall pass rate of Thomas High School to 65% before the student total was adjusted correspondingly.
• Recovery of the actual test scores for the ninth graders of Thomas High may have a greater effect on the data overall.
