Question 1

A school leader analyzes graduation rate data and finds it improved from 78% to 88% over five years. To determine if this is a meaningful improvement, the leader should calculate:

Accepted Answer

An effect size or confidence interval to assess practical and statistical significance

Answer

Effect size and confidence intervals help determine whether an observed change is statistically meaningful rather than due to chance variation.

Question 2

When designing a school survey to gather stakeholder input, which practice MOST threatens the validity of the data collected?

Accepted Answer

Including leading questions that imply a preferred response

Answer

Leading questions bias respondents toward a particular answer, undermining the validity and reliability of survey findings.

Accepted Answer

Both A and C

Answer

Both regression to the mean (students with unusually low scores tend to score higher on retest) and test difficulty changes are alternative explanations for score gains.

Question 4

Which stakeholder communication strategy BEST supports data literacy among parents?

Accepted Answer

Translating data into plain language with concrete examples of what scores mean for learning

Answer

Plain-language explanations with concrete learning implications empower parents to understand and act on assessment data.

Question 5

Accepted Answer

Comparing current performance data against desired performance targets to identify discrepancies

Gap analysis identifies the difference between where students currently perform and where they need to be, guiding improvement priorities.
