Current Performance

Why Growth?

─ Proficiency

One way to compare student performance on tests across teachers’ classrooms is to observe student proficiency at the end of the year. Based on this information alone, whose students had a better year?

Page 9: State-Calculated Growth Measures Overview

Why Growth?

By adding in prior performance (blue bars), we can see how much a student grew from last year to this year. With this additional information, now whose students had a better year?

How to Measure Growth?

• Test score scales are not comparable across grades.

• Difficult to measure growth directly.

• Example: Last month I had $100 in my checking account. This month I have 85 Euros. How much money have I gained or lost?

• Extra credit: I have about $11 or 8€ more this month than last.

EngageNY.org 10

Page 11: State-Calculated Growth Measures Overview

How to Measure Growth?

• Starting point matters.

• Just knowing how much growth happened may not be enough. Need a system that provides fair comparisons.

• Example: Her hair grew one inch last month.

• So did his.• Whose hair growth

seems more impressive?

Student A’s Current Year Performance Compared To “Similar” Students

If we compare student A’s current score to other students who had the same prior score in 2012, we can measure her growth relative to other students. We describe her growth as a “student growth percentile” (SGP). Student A’s SGP is the result of a statistical model and in this example is 45, meaning she performed as well or better in the current year than 45 percent of similar students. SGPs range from 1-99.

Student E’s Current Year Performance Compared To “Similar” Students

We can make similar comparisons for other students with different prior test scores. Notice that students with relatively low prior scores, like student A, can have high SGPs, as can students with high starting scores, like student E. Students with similar current year scores can have very different SGPs. Students with high SGPs may not reach proficiency.

Change in Scale from 2011-12 to 2012-13

• Scale scores will be different this year from last year

New assessments are aligned to the Common Core State Standards

• Growth scores can still be calculated with different scales across years

They provide a valid measure of the relative performance of similar students who took the old test in the prior year and the new test this year

Student Growth Percentiles: True or False?

1. A student with an SGP of 50 performed as well or better than 50 percent of similar students.

2. A student with an SGP of 80 must be proficient.

3. A student with an SGP of 20 grew less than a student with an SGP of 60.

4. The highest SGP that a student can receive is 99.

5. A student with an SGP of 75 got about 75% of test questions correct.

Defining “Similar Students”

We include data about four characteristics (circled in blue here) when we compare student growth. These factors allow us to more precisely separate the impact of things that a teacher does not control from the effects of the instruction.

Student performance

Economic disadvantage

(poverty)

Instruction

Disability (SWD)

Academic history

Language proficiency

(ELL)

Page 17: State-Calculated Growth Measures Overview

Expanding the Definition of “Similar” Students: An Example

Previously, we compared all students with the same prior scores to measure growth for Student A.

Now we expand the definition of “similar” to include other characteristics, such as whether or not the student is economically disadvantaged.

Now the comparison group for Student A includes students with the same prior score AND who are economically disadvantaged. Student A now has an SGP of 48. Students with each of the characteristics used to define similar students can have a range of SGPs.

Note that this example simplifies the actual statistical calculations that occur when many factors are used in these measures.

and not achievement• Be fair to teachers – ensure all teachers can demonstrate

effectiveness regardless of composition of class or school; take into account not just achievement at one point in time.

Describe how the State is measuring growth compared to similar students• Compare students based on academic history, English

language learner (ELL) status, disability status (SWD), and economic disadvantage (poverty).

Page 25: State-Calculated Growth Measures Overview

Mean Growth Percentile

• Main educator measure is Mean Growth Percentile or MGP.

Average of SGPs associated with an educator • Tells us on average how a teacher or principal’s

students did compared to similar students. Example: An MGP of 51 means that on average this

teacher’s students perform better than 51 percent of similar students.

• Reports will display “unadjusted” and “adjusted” MGPs. Adjusted MGPs account for similar student characteristics and are used for evaluation.

NoExample:Student A is enrolled in a course for 80% of the course and attends for 90% of that time – attendance duration is calculated as 0.8 x 0.9 = 0.72. Student A’s SGP is then weighted by 0.72 in her teacher’s MGP.

Student C 70 50% 80% N/A

Student D 60 100% 90% .90

Student E 40 100% 55% .55

3.12

To measure teacher performance, we find the mean growth percentile (MGP) for her students, which is the weighted average of the SGPs. In this case:

Step 1: (.72*45)+(.95*40)+(.90*60)+(.55*40)=146.4Step 2: .72+.95+.90+.55 = 3.12Step 3. 146.4 / 3.12 = 46.9

Ms. Smith’s mean growth percentile (MGP) is 46.9, meaning on average her students performed as well or better than about 47 percent of similar students.

Page 29: State-Calculated Growth Measures Overview

Minimum Number of Scores Required for Reporting Teacher MGPs

• In order for an educator to receive a growth score, he or she must have a minimum sample size of 16 student scores in ELA or mathematics across all grades he or she teaches.

• If an educator does not have 16 student scores, he/she will not receive a growth score from the State.

Educators likely to have fewer than 16 scores should have student learning objectives (SLOs).

• Examples included in appendix, along with information about rosters of student-level data that will be available for authorized educators in AIR’s Growth Reporting System.

Same minimum sample size requirements (16 student scores) for principals as for teachers.

To measure principal performance, we find the mean growth percentile (MGP) for all her students who were enrolled on BEDS and assessment day. To find a principal’s mean growth percentile, take the average of SGPs in the school:

Step 1: 45+40+70+41=196

Step 2. 196/4=49.

Principal Jensen’s mean growth percentile (MGP) is 49, meaning on average her students performed as well or better than 49 percent of similar students.

From Teacher and Principal MGPs to HEDI Ratings and Scores

Page 34: State-Calculated Growth Measures Overview

MGPs and Statistical Confidence: Teachers and Principals

• New York State Education Department (NYSED) will provide a 95 percent confidence range, meaning we can be 95 percent confident that an educator’s “true” MGP lies within that range. Upper and lower limits of MGPs will be used when classifying educators into HEDI categories.

• An educator’s confidence range depends on a number of factors, including the number of student scores included in his or her MGP and the variability of student performance in the class or school.

Glossary of Variable Definitions• Poverty - A student considered in poverty is a one who participates in, or whose

family participates in, economic assistance programs such as Free/Reduced Lunch, Food Stamps, SSI, EITC, etc.

• Average prior achievement in class/course (same subject)—the average prior same-subject achievement on the state assessment of all students attributed to a teacher in the current year.

• Prior-year different subject test score—a student’s prior-year scale score on the state assessment in the other subject.

• Students spend less than 40 percent or more of their time in general education—a categorical indicator of the percent of time a student spends in a general education setting for the entire day. Per IDEA requirements, the student should spend as much time as possible in a general education setting; this categorical variable is reported to the U.S. Department of Education.

• Percentage of students in poverty, ELLs, and SWDs in class/course—the percentage of students in a teacher’s class/course that meet the definition for any one of these characteristics.

• Class/course size—the number of students attributed to a teacher in a class/course.

EngageNY.org 55

Page 56: State-Calculated Growth Measures Overview

Glossary of Variable Definitions• Heterogeneity of class/course in terms of achievement —an indicator of the

magnitude of difference in average prior achievement in a teacher’s class/course, calculated as the interquartile range in average prior achievement of the classroom (same subject).

• NYSESLAT (for use as a predictor of language proficiency)—an indicator of English language proficiency in listening/speaking and reading/writing.

• Over or under age (different from modal age)—a continuous indicator of the extent to which the student is over or under age for his/her grade. It is calculated as the difference in the student’s age from the modal age for the grade.

Page 58: State-Calculated Growth Measures Overview

Minimum Number of Scores Required for Reporting 4-8 Teacher and Principal

MGPs • In order for an educator to receive a growth score, he or she must

have a minimum sample size of 16 student scores in ELA or mathematics across all grades he or she teaches.Examples:

A teacher has a self-contained classroom with eight students who take the Grade 4 ELA and mathematics assessments; this teacher would then have 16 student scores contributing to his or her growth score.

A teacher has a class with 12 students who are in various grades (e.g., fourth, fifth, and sixth) who take the ELA and mathematics assessments for their respective enrolled grade level; this teacher would then have 24 student scores contributing to his or her growth score.

• If an educator does not have 16 student scores, he/she will not receive a growth score from the state.

Educators likely to have fewer than 16 scores should have student learning objectives (SLOs).

MGP FOR ELA AND INTEGRATED ALGEBRA REGENTS EXAMS

Page 63: State-Calculated Growth Measures Overview

Why This Metric?

• A principal’s score reflects student academic growth on Regents Exams compared with other similar students.

• Integrated Algebra and ELA Regents Exams are the most commonly taken exams.

On average, about 46 percent of students in a high school are included in an ELA or algebra growth measure.

• Passing each exam is required for graduation and achieving higher than passing scores signals college and career readiness.

MGP for ELA and Integrated Algebra Regents Exams: Same Approach as Grades 4–8 MGP

Measures

EngageNY.org 64

Comparing Student A’s Regents Algebra Exam score to other students who had the same eighth- grade mathematics score (640 scale score), she earned an SGP of 58, meaning she performed as well or better in the current year than 58 percent of similar students.

SGPs are averaged to get a school’s MGP.

Additional Details About 9-12 MGP Metric

• Which test scores count? Count Regents Exam scores from August of prior year (except for ninth

graders), January, and June. Choose the higher of test scores within these administrations. Student scores count up until they pass (after students pass, we do not want the

measure alone to encourage additional test taking, which may not be necessary).

• Which students are included? Students who take either exam during the year and are attributed to the school

using NYSED’s rule for minimum enrollment. Students are included up to eight years after first entering ninth grade. Students who take the Integrated Algebra or ELA Regents Exams prior to high

school are NOT included in the MGP of a principal of Grades 9–12.

• What kind of scores would be reported? An MGP will be reported for a principal for ELA, Algebra I, and an overall MGP

(as long as minimum N sizes are met for each subject area).

COMPARATIVE GROWTH IN REGENTS EXAMS PASSED MEASURE

Page 67: State-Calculated Growth Measures Overview

Why This Metric?

• A major graduation requirement for students is to pass five Regents Exams; advanced Regents diplomas require more than five.

• This measure compares how much progress the school’s students are making from one year to the next toward passing up to eight Regents Exams.

On average, about 84 percent of students in a high school are included in the Comparative Growth in Regents Exams Passed measure.

• A principal’s score reflects whether or not his or her students exceed the average change in number of Regents Exams passed each year achieved by similar students statewide.

Additional Details about 9-12 Comparative Growth in Regents Passed Metric

• Which test scores count? Count Regents Exam scores from August of prior year, January, and June. Choose the higher of test scores within these administrations on same tests. Student scores count up until they pass (after students pass, we do not want the

measure alone to encourage additional test taking, which may not be necessary).

Five required Regents and no more than three others will count. Passing score rules for SWDs are accounted for.

• Which students are included? All students attributed to a school using NYSED’s rule for minimum enrollment,

whether or not they take a Regents Exam during the year. Students are included up to eight years after first entering ninth grade. Students who exceed eight Regents Exams passed are NOT included in a

Grades 9–12 principal’s results. Dropouts are counted until they have reached their fourth year since entering

ninth grade, starting with the 2012–13 school year.

Determining HEDI Ratings and Scores for Grades 9–12 Principals

• The following steps will be taken to determine each principal’s HEDI rating and score:

1. HEDI rating and scores will be calculated for each measure separately using the same criteria used for Grades 4–8 principal growth measures (see next slide).

2. HEDI scores are weight-averaged based on the number of student results in each measure.

3. Resulting score determines combined HEDI rating.

4. For schools with only one measure, the growth subcomponent rating (HEDI) and score are derived from the Grades 9–12 measure that can be calculated for them (Comparative Growth in Regents Exams Passed or Combined MGP).
