NSCAS Growth Measures 3

Question 1

When educators review NSCAS Growth data for a classroom, a 'median SGP' is often used. What does the median SGP represent?

Accepted Answer

The middle growth percentile when all student SGPs are ranked

Answer

The median SGP is the middle value of all individual student growth percentiles in a group, making it resistant to extreme outliers.

Question 2

A school's median student growth percentile in ELA is 35. How should this be interpreted?

Accepted Answer

The typical student grew less than most academically similar students statewide

Answer

A median SGP of 35 means the typical student in that school grew less than 65% of academically similar students statewide, indicating below-average growth.

Question 3

Which factor does the NSCAS Student Growth Percentile model explicitly control for?

Accepted Answer

Prior academic achievement levels

Answer

The SGP model controls for prior achievement by comparing students only to peers who had the same prior-year score history, not demographic factors.

Question 4

A student who scored 'Below Proficient' last year and earns an SGP of 60 this year should be described as:

Accepted Answer

Performing below grade level with above-average growth

Answer

The student is still below proficiency (status) but grew more than 60% of similarly-scoring peers, showing above-average growth relative to their starting point.

Question 5

For NSCAS Growth Measures, how many years of test data are needed to calculate a Student Growth Percentile?

Accepted Answer

At least two consecutive years of scores in the same subject

Answer

A minimum of two consecutive years of scores in the same subject are required to calculate growth by comparing prior and current performance.
