SGP Analysis To Be Performed in 2023
• Following what was performed in 2022, in 2023, the same two
types of SGP analyses will be conducted with SBA and WIDA-
ACCESS data:
• Cohort referenced analyses: These analyses create growth norms from
the 2021, 2022, and 2023 students. We are back to two prior data point
“post”-COVID. These growth norms yield cohort means/median SGPs of
50 and obscure COVID-19 academic impact.
• Baseline referenced analyses: Historical growth norms were created using
2017, 2018 and 2019 data. These growth growth analyses don’t have
mean/median SGPs of 50 and can be used to investigate overall COVID-19
academic impact and recovery.
SGP Analysis Plans for 2023
• Cohort referenced SGPs
• Growth norms created from the current cohort of students.
• Mean/median will by 50 for all grade x content area analyses
• Cannot investigate overall impact & recover of the pandemic on students.
• Can investigate differential impact & recovery of the pandemic on students.
• Does not require scale stability across years.
• Projections possible
• Baseline referenced SGPs.
• Growth norms created from historical (i.e., pre-COVID) cohorts of students.
• Mean/median 50 for historical cohort, not necessarily 50 for current cohort.
• Extent of deviation from (i.e. below) 50 is indicative of less learning/pandemic related academic impact.
• Mean SGP deviation of 5 corresponds to an effect size of 0.18.
• Can investigate BOTH overall impact & recovery as well as differential impact & recovery.
• Requires scale stability across years.
• Projections possible
Growth for Accountability in 2023
SGP for Accountability
• Growth results for 2022 (baseline referenced) were promising indicating rates
of learning in excess of what was observed in the state prior to the pandemic.
• That is, students, on average, are recovering.
• The hope is that growth (baseline referenced) in 2023 will be at least a good
as 2022.
• Hawaii will received both cohort and baseline reference SGPs.
• These can be summarized in a number of ways:
• Mean or Median SGP
• Percent of students above a threshold or percent making or exceeding a
year’s worth of learning.
Growth for Supplemental Reporting in 2023
SGP Analysis Plans post 2021 (2023 and beyond)
• Spring 2021 represented (probably) an ideal time to get a snapshot of
student attainment as we were presumably at or near the point of
maximal impact on student attainment.
• That is, recovery had not really begun for most students in earnest.
• It’s impossible to talk about recovery sensibly without understanding
how big the impact is.
• Monitoring recovery will be at least as critical as monitoring the
impact of the pandemic on student achievement.
• Beware the K-shaped recovery!
SGP Analysis Plans for 2023
• Conduct analyses of recover in line with what was done in 2022.
• Examine the extent to which recovery is continuing including how
schools are performing.
Pandemic Related Academic Impact
• As stated previously, any discussion of recovery implies some
understanding of what the impact is/was.
• As a basis for investigating academic impact/recovery, we undertook a
comprehensive look at academic impact in Hawaii
• SBA: Determined academic impact from 2019 to 2021 using grades 3,
4, 5, 6, 7, and 8 in ELA and mathematics.
• WIDA-ACCESS: Determined academic impact from 2020 to 2021
using grades K to 12 ELP
How do we quantify academic impact using test data
• The pandemic was like a “headwind” that (presumably) slowed down the learning of
students due to a variety of factors.
• We can use test data in two ways to quantify the impact of this headwind:
• Best way: Quantify how much the rate of learning (i.e., growth) slowed:
• SBA: Use historical skip-year growth norms to quantify growth and compare to pre-COVID growth.
• ACCESS: Use historical consecutive-year growth norms and compare to pre-COVID growth
• Next best way: Look at how much 2021 status changed:
• SBA: Use 2019 status (or some adjustment thereof) as a proxy.
• ACCESS: Use 2020 status (or some adjustment thereof) as a proxy.
• Adjustments include (potentially) imputation for missing data
