A Growth Measure for ALL Students

Outcomes Review the Center’s growth measure Student Growth Percentile (SGP) 2. Understand the methodology for Median Growth Percentile (MGP)

Data Overload Often times, Board members are inundated with mounds of data that, if not analyzed or presented well can lead to the “wrong” message being communicated about student achievement and growth.

Prepare students academically for success in college, work and life The Educational Goal Prepare students academically for success in college, work and life Measure 1: Student Achievement The Center, as a service to Boards and administrators provide clear expectations (metrics and measures) as well as a helpful analysis and presentation of the school’s data in the annual Academic Performance Report (APR). If you have not previewed your school’s 2014-15 academic data, please connect with your school lead. Included in the APR, is the school’s Educational Goal (Prepare students academically for success in college, work and life) as well as the measures for student achievement and student growth. In order to assist schools in monitoring progress toward the Educational Goal of the Charter Contract, the Center has provided achievement targets for grades 2-8 for both Performance Series and NWEA’s Measures of Academic Progress (MAP) assessments. In addition, you receive a display of student growth. Measuring growth toward a meaningful standard, like a college readiness achievement target, will demonstrate whether students are growing the necessary amount to be college ready. TRANSITION: These measures and metrics are intended to support you in your work at the school. Measure 2: Student Growth

We will continue to focus on achievement AND growth We will continue to focus on achievement AND growth. This is NOT an EITHER / OR

The Right Focus The Right Time The Right Outcome Three things that we will consider throughout the coming year will be… The RIGHT FOCUS The RIGHT TIME The RIGHT OUTCOME

The Right Focus The Right Time The Right Outcome Student Growth 2016-17 The Right Outcome Increase monitoring of student learning We believe this is The RIGHT FOCUS because it assists us as an authorizer in understanding how the Academy’s implementation, delivery and support of the Educational Program of the Charter Contract is assisting students in academic growth. The RIGHT FOCUS for Boards because you will know have a way to monitor the Academy’s implementation, delivery and support of the Educational Program of the Charter Contract and its impact on student academic growth. The RIGHT TIME because the stakes are so high for students and we, as the authorizer, are committed to ensuring that each Academy is “fostering academic excellence for all students.” We have a moral imperative to redeem the time that we have with these children to ensure that they are given the highest quality education possible. The RIGHT OUTCOME ensures that the Academy meets the Educational Goal of the Charter Contract, “to prepare students for college, work, and life.” This student growth measure gives you power as a Board to ask the question, “Are our students growing academically at a rate that would ensure that they are successful in college, work and life? If not, then what are we going to do about it?

Student Growth Measures Method for determining how much academic progress a student has made by measuring growth between two points in time (i.e., fall to spring) The definition for student growth is…method for determining how much academic progress a student has made by measuring growth between two points in time (fall to spring) We have continued to be focused on the academic growth of all students. This is the same focus we have had in the Charter Contract for years - NOTHING HAS CHANGED.

Student Growth Percentiles As we examine a growth measure for students, we are interested in a measure that compares the growth of all students. It is important to the Center that this comparison is an apple-to-apple comparison. We want to see how students of similar academic skills are growing. That leads us to the measure: student growth percentile Student growth percentiles calculate how a student’s performance on a national standardized assessment compares to the performance of all students who received the same score in the fall (test score peers). Student growth percentiles (SGP) calculate how a student’s performance on a national standardized test compares to the performance of all students who received the same score in the fall (test score peers).

Student Growth Percentiles Let’ s take a look at John Dough a 4th grade student in your school John “Dough” – 4th grade

Student Growth Percentiles fall score 195.5 We are looking to compare John Dough’s score with other 4th grade students that have taken the same assessment. Instead of comparing John Dough to ALL 4th graders, we are looking for students that have a similar score to John Dough. These are called John Dough’s test score peers.

Student Growth Percentiles 195 195 195 195 Student Growth Percentiles 195 195 195 195 195 195 195 195 195 We have now found all the 4th grade students that scored the same on the assessment in the fall. They all scored 195. Now fast forward - A complete year of instruction ensues and the teachers and support staff work with John Dough as well as all other students in the school for an entire year. In the spring John Dough and all the other 4th graders take another assessment. We are now interested in seeing how John Dough did compared to his test score peers (those of similar academic ability).  

Student Growth Percentiles fall score 195.5 spring score 207 This time, John Dough scores a 207. We now ask ourselves the all-important question.   How did John’s test score peers do on the assessment?

We can understand this by assigning each student a student growth percentile. This is a percentile associated with the amount of growth students achieved from fall to spring. Notice that each SGP is different because their fall to spring scores were different.

99 92 89 85 85 70 54 50 45 10 5 33 20 We can see that each SGP is different because their fall to spring scores were different.

89 An SGP of 89 would indicate that John “Dough” performed better than 89% of his test score peers From this SGP, we are able to see that, compared to his test score peers (students with similar test scores in the fall), John’s SGP is 89. That means that compared to his test score peers John did better than 89% of his peers. John would be considered to have greater, or high growth.

Making the Soup There is no secret recipe for the Center’s growth measure; however, we thought it would be helpful if you understood the methodology. When examining our work on student growth, we asked three important questions…

Three Key Questions How do we know the gain between fall and spring for each student? How does the gain compare to what is typical from the norming sample? How are the Academy students performing as a group? Read questions from the slide.

Question 1 1 How do we know the gain (growth) between fall and spring for each student? Read information on the slide

Question 1 1 How do we know the gain (growth) between fall and spring for each student? Take the student’s spring scaled score and subtract the fall scaled score. Read information on the slide

Question 2 2 How does the gain (growth) compare to what is typical from the norming sample? Read information on the slide

Question 2 2 How does the gain (growth) compare to what is typical from the norming sample? Divide the difference (the gain) by the standard deviation of the gains. z scores growth percentiles Read information on the slide

How are the Academy students performing as a group? Question 3 3 How are the Academy students performing as a group? Read information on the slide

How are the Academy students performing as a group? Question 3 3 How are the Academy students performing as a group? Order every student that has a student growth percentile from lowest to highest and calculate the median growth percentile. Read information on the slide

Student Growth Percentile Median Growth Percentile Contrast Student Growth Percentile Median Growth Percentile We will take a moment to contrast Student Growth Percentile with Median Growth Percentile.

Student Growth Percentile Median Growth Percentile Contrast Student Growth Percentile Percentile calculated for an individual student’s growth Median Growth Percentile Student growth percentile is the percentile calculated for an individual student’s growth. Each student in grades 3-8 will have a student growth percentile that is derived from the difference between the fall and spring NWEA MAP or Performance Series assessment.

Student Growth Percentile Median Growth Percentile Contrast Student Growth Percentile Percentile calculated for an individual student’s growth Median Growth Percentile Percentile calculated for a school based on student growth percentiles of ALL students in grades 3-8 The median growth percentile is calculated for a school based on student growth percentiles of ALL students in grades 3-8. Each school in the CMU-portfolio will have a median growth percentile for the content areas of reading and math.

Median Growth Percentile 99 98 94 90 89 87 84 79 76 65 52 43 40 32 24 10 4 Median Growth Percentile Student growth percentiles (all students grades 3-8) are ordered from lowest to highest Now we are going to take a moment to look at median growth percentile. When we are calculating a school’s median growth percentile, we begin with the individual student growth percentile. We take all the student growth percentiles of individual students in grades 3-8 and order them from lowest to highest.

SGP’s listed are a representative sample for presentation purposes. 99 98 94 90 89 87 84 79 76 65 52 43 40 32 24 10 4 Median Growth Percentile SGP’s listed are a representative sample for presentation purposes. An Academy could have SGPs ranging from 1-99. These SGPs are for ALL students tested in grades 3-8 Read information on the slide It is important to remember that there will be an SGP for each individual student in grades 3-8. If the school has 312 students in grades 3-8, then the school will have 312 SGPs. These SGPs can range from 1-99. When calculating median growth percentile, the SGPs will be ordered from lowest to highest.

Median Growth Percentile 99 98 94 90 89 87 84 79 76 65 52 43 40 32 24 10 4 Median Growth Percentile Student growth percentiles (grades 3-8) are ordered from lowest to highest Median growth percentile summarizes the school’s growth with students in a particular subject area (reading/math) If you think about median being the middle that will assist you in understanding the foundation of median growth percentile. The Center will take the individual student growth percentiles of ALL students tested in grades 3-8 for each content area of reading and math. The SGPs will be ordered from lowest to highest. The median, or middle SGP, for all students will be identified. This median growth percentile summarizes the school’s growth with students in a particular subject area (reading/math). When using this example on the slide, this would indicate that this Academy’s median growth percentile is 76. This summarizes that the school is demonstrating high growth for their students. Yes, there are many student’s SGPs that are low; however, the number of students that have high SGP’s causes the school to have a higher median growth percentile – remember we are looking for the median (middle SGP) for all students in grades 3-8. The greater the growth for individual students, the higher the median growth percentile.

How might you explain median growth percentiles to a parent?
