Using NAPLAN summative data to identify instructional successes and challenges. Presented by Philip Holmes-Smith School Research Evaluation and Measurement Services
Overview of Session • Using NAPLAN summative data to identify instructional successes and challenges • Understanding the National Scale, • School Summary analysis, • Five-Year Trend analysis, • Individual student-level data analysis • Value added (Growth) analysis
Understanding the National Scale • The National Scale is an arbitrary scale – at this stage it is not related to points along a developmental curriculum. But, it is highly likely that it will be mapped onto the National Curriculumat some time in the future.
Understanding the National Scale • The National Scale is an arbitrary scale – at this stage it is not related to points along a developmental curriculum. But, it is highly likely that it will be mapped onto the National Curriculumat some time in the future. • The National Scale was fixed in 2008as follows: • Range: 0-1000 • Mean: 500 • Standard Deviation: 100 (i.e. 68% students between 400-600) 900 800 +1 STD 700 600 2008 National Mean 500 400 -1 STD 300 200 100

Victorian State Averages - 2011(By Year Level and Dimension)
Cautionary Note #1 • Equal scores amongst different dimensions (on the National Scale) do not equate toequal levels of performance in terms of expected VELS levels. e.g. • A National Yr9 Reading score of 586.6 is equivalent to a VELS score of 5.25, but • A higher National Yr9 Numeracy score of 592.5 is equivalent to a lower VELS score of 4.82.
Comparing National Scale Scores to Estimated VELS Equivalent scores • The Victorian means for Year 3 and Year 9 Reading and Numeracy on the National scale are compared to the estimated VELS equivalent scores below: • Compared to our expected curriculum outcomes for Year 3 students (2.175), the State Reading mean is about 1½ term ahead of where we expect a typical Year 3 student to be. However, the State Numeracy mean is about 2½ terms below where we expect a typical Year 3 student to be. • Compared to our expected curriculum outcomes for Year 9 students (5.175), the State Reading mean is just above where we expect a typical Year 9 student to be. However, the State Numeracy mean is about 2½ terms below where we expect a typical Year 9 student to be.

Cautionary Note #2 • “Estimated VELS Equivalent Scores” should be viewed with caution. Specifically: • It is doubtful that the “Estimated VELS Equivalent Scores” for Writing,Spelling or Grammar & Punctuation are truly VELS scores. (The writing marking rubric does not use VELS criteria and there are no VELS criteria for Spelling or Grammar & Punctuation.) • “Estimated VELS Equivalent Scores” are based on an equating study that is now three years old.

Interpreting “box and whisker” graphs 3 students on or above the 90th percentile. (Note, all we know is at least one student scored on the 90th percentile.) • There are 30 students in this Year Level. Therefore: • 50% (or 15 students) are above the median. • 50% (or 15 students are below the median. • 50% (or 15 students) are inside the “box”. Half of these (7-8 students) are above the median and half (7-8 students) are below the median. • 10% (or 3 students) are at or below the 10th percentile “whisker”. • 10% (or 3 students are at or above the 90th percentile “whisker”. • 15% (or 4-5 students) are spread between the 25th down to the 10th percentile. • 15% (or 4-5 students) are spread between the 75th up to the 90th percentile. ? ? 15 students above median 4-5 students between the 75th up to the 90th percentile. 7-8 spread above the median. 15 students inside the box. 7-8 bunched below the median. 4-5 students between the 25th down to the 10th percentile. 15 students below median 3 students on or below the 10th percentile.

Interpreting the School Summary Report • Is the school’s median above, at or below the State median? School’s median is about half a band below the State median
Interpreting the School Summary Report • Is the school’s median above, at or below the State median? • For VELS only, is the Reading median above, at or below the Numeracy median? School’s median is about half a band below the State median Reading is higher than Numeracy
Interpreting the School Summary Report • Is the school’s median above, at or below the State median? • For VELS only, is the Reading median above, at or below the Numeracy median? • How does the school’s spread compare to the State spread? School’s median is about half a band below the State median Reading is higher than Numeracy School has far fewer high performers than the State School’s median is at the State’s 25th percentile School has far more low performers than the State

Growth Analysis (NAPLAN scale) Letitia appears to have grown 163.6 units from 436.8 in Yr3 to 600.4 in Yr5. Javier appears to have gone backwards 40.7 units from 506.2 in Yr3 to 465.5 in Yr5.
Growth Analysis (NAPLAN scale) On Average, the school has grown its students 66.79 units compared to the State’s 83.2 units. This is 16.41 units less than the state.
Growth Analysis (VELS scale) Letitia appears to have grown 1.64 VELS units from 2.52 in Yr3 to 4.16 in Yr5. Javier appears to have gone backwards 0.43 VELS units from 3.11 in Yr3 to 2.68 in Yr5.
Growth Analysis (VELS scale) On Average, the school has grown its students 0.68 VELS units compared to the State’s 0.84 VELS units. This is 0.16 VELS units less than the state.
Growth Analysis (VELS scale) Difference scores show how much more or less growth you show compared to the State growth This year’s growth appears to be part of an worsening trend compared to the State growth
