About the Data
A student is assigned to a permanent four year and six year graduation rate cohort based on two factors:
- School year of the student’s first high school enrollment period in Wisconsin, and
- Student’s grade level placement at the time of that first high school enrollment period.
To be counted as a graduate under the four-year adjusted cohort rate, a student must earn a regular diploma on or before the summer following their fourth year of high school. This includes early graduates.
To be counted as a completer under the four-year adjusted cohort rate, a student must earn a regular diploma, high school equivalency diploma, or other high school completion credential on or before the summer following their fourth year of high school. This includes early completers.
Until 2011-12 rates are available five-year rates will be provided in lieu of six-year rates.
High School Completion Rates and Final Cohorts. All data come from Individual Student Enrollment System (ISES) Year End records. The key records used for cohorts and rates are typically the ISES record when the student initially enrolls in a high school grade and that student’s most recent ISES record as of the end of his or her cohort’s four-year or six-year rate timeframe.
Projected Cohorts. Until final ISES Year End records are available for the school year at the end of the rate timeframe, final cohorts cannot be determined. Data for projected cohorts are based on ISES Year End records early in the timeframe supplemented by more recent data for the same students from a variety of sources. The Wisconsin Student Locator System (WSLS) is used to determine the projected accountable school until ISES Year End records for the school year that most recently ended are finalized. WSLS, ISES Third Friday of September, and/or WSAS records may be used for projected student group identification purposes.
Time to High School Completion. All data about high school completion come from ISES Year End records for the selected school year. All data about time (to high school completion) is based on each student’s first high school enrollment record in ISES regardless of year.
A tipsheet and check list is available to assist ISES administrators in verifying that data used in HS Completion dashboards are correct.
How the Data are Reported in WISEdash
High School Completion Rates: HS Completion Rate metrics are based on the federally-required Title I adjusted cohort rate formula. All students included in the calculation of these rates are part of a statewide cohort. Students are assigned to a statewide cohort when they first enroll in a high school grade. In general, district and school cohorts are determined based on where students in the statewide cohort were last enrolled during the 4 or 6 year timeframe following the creation of the statewide cohort. Four-year and six-year rates are published for the school year at the end of each timeframe and reflect each student’s completion status as of the end of that school year.
- HS Completers – 4 Year Rate. This metric indicates that the percentage of students in the cohort who received any HS completion credential during the 4-year timeframe. Completers include students earning credentials in less than 4 years. The credential categories are “regular diploma”, “HSED” (high school equivalency diploma), and other (e.g. certificates of attendance and completion).
- HS Completers – 6 Year Rate. This metric indicates that the percentage of students in the cohort who received any HS completion credential during the 6-year timeframe. Completers include students earning credentials in less than 6 years. The credential categories are “regular diploma”, “HSED” (high school equivalency diploma), and other (e.g. certificates of attendance and completion). The 6 Year Rate for Year X includes the same students as the 4 Year Rate for Year X-2 with adjustments made for certain changes in student status between the end of year 4 and end of year 6. Note: Until 2011-12 rates are available Five Year Rates will be provided in lieu of Six Year Rates.
- HS Noncompleters – 4 Year Rate. This metric indicates the percentage of students in the cohort who did not earn any HS completion credential during the 4-year timeframe. The categories are “known to be continuing”, “reached maximum age” and “not known to be continuing”.
- HS Noncompleters – 6 Year Rate. This metric indicates the percentage of students in the cohort who did not earn any HS completion credential during the 6-year timeframe. The 6 Year Rate for Year X includes the same students as the 4 Year Rate for Year X-2 with adjustments made for certain changes in student status between the end of year 4 and end of year 6. Note: Until 2011-12 rates are available Five Year Rates will be provided in lieu of Six Year Rates.
High School Completion Cohorts: This table provides a convenient way to view all the recent final and projected cohorts. Users with proper authorization can select a cohort described by any row and view student level details for that cohort. Rate Inclusion Indicators are calculated for each student prior to calculating rates and document exclusion of any student who transferred to another state or nonpublic school, emigrated to another country, or died before the end of the rate timeframe.
- Final Cohorts. This list includes student level details about all students in the selected cohort. Students in the list with “Rate Inclusion Indicator = Included” are the students in the cohort used for the High School Completion Rates. Rows are also included for students with “Rate Inclusion Indicator=Excluded” so users can understand which students are counted in rates and which are not.
- Projected Cohorts. This list includes all students in a selected cohort prior to availability of final ISES Year End data for the school year at the end of the rate timeframe. This cohort is subject to change between the current date and the availability of final data. Note that
- Projected cohorts do not include any students new to the statewide cohort after the most recent year of final ISES Year End data because only Year End data are used for statewide cohort assignment purposes. This means that high school students who transferred into your district from outside Wisconsin public schools may be included in that cohort but not yet appear in the projections.
- Projected cohorts tend to be larger near the end of the timeframe than at the beginning. This is because the cohort initially consists only of first time 9th graders. With each successive year of the timeframe, students who initially enter the cohort at higher grade levels are added to the cohort. These students generally come from private schools or out of state.
- The projected 6-year cohort for School Year X is the same as the most recent final 5-year cohort for School Year X-1 if it exists or, if not available, the final or projected 4-year cohort for School Year X-2.
- Rate Inclusion Indicators are not calculated until the final data are available so are not available for Projected Cohorts.
Time to High School Completion: This dashboard shows how many students earned completion credentials in a selected year and how long it took for them to earn those credentials. Time is the number of years since a student was a first time ninth grader until the selected year. For students who entered a statewide cohort after ninth grade, time is the number of years since the statewide cohort was created. Only students who earned completion credentials in the selected year are counted.
- For students who initially enrolled in high school before 2006-07, time to high school completion is reported as “Years Unknown” because data about time to completion were not available in ISES until 2006-07. Limited data about time to completion were available between 2006-07 and 2010-11. Complete data were not available until 2011-12.
- Counts of students who earned completion credentials match those counts used in calculating legacy high school completion rates for the same school year. Due to formula differences, these counts may or may not match counts of completers used in calculating four-year and six-year rates for the same school year.
Definitions and Formulas
- Definitions of terms used in WISEdash (FOR DISTRICTS) High School Completion dashboards can be found in the WISEdash Glossary for WISEdash Public Portal
- Formulas used in calculating adjusted cohort rates can be found on the About the Data - High School Completion webpage under Counting Students and Calculating Rates. Although About the Data - High School Completion is designed for use with WISEdash Public Portal, the formulas for calculating adjusted cohort rates are the same as those used in WISEdash (FOR DISTRICTS). There may be very small differences in counts used to calculate rates due to the dynamic nature of data sets used for WISEdash (FOR DISTRICTS).
