Florida's school grading system is the oldest in the nation, and has undergone dozens of changes to the way grades are calculated since it was first implemented in 1999. This year the state will once again need to make some significant changes to the formula to reflect new standards and assessments being adopted.
Recently, we released a policy brief outlining some broader changes we believe the state should consider during this process to make grades more stable and meaningful moving forward. Now you can use the interactive visualization below to see what the impact of some of those changes might mean for the state, your district, or your school.
In our policy brief, Understanding and Updating School Grades for Florida's Future, we explore five major recommendation areas we believe the state should be considering during this unique opportunity in order to resolve some of the most persistent concerns about the current school grading model in recent years. Those areas are:
In the visualization below, you can use the drop-down menus on the right-hand side to see what the impact would be in terms of total points earned and grades assigned for some different combinations of some of these suggested changes.
It is important to note that due to data limitations, the options below only reflect some of the suggested options to consider outlined in the brief. For example, under the recommendation area "Emphasize student growth, and measure it over multiple years instead of just one." we detailed multiple potential alternatives for measuring growth, including multi-year averages, cohort models, and value-added modeling. Because access to the raw data that would be required to measure the impact of potential cohort or value-added models is not publicly available, the visualization below only includes the option of different multi-year averages of current growth score calculations. We recommend reading the full policy brief to get a more complete sense of all the options we believe the state should be considering during this process.
Despite these limitations, the visualization can help provide a clear sense of what the impact would be of making certain changes in how growth is calculated, how much growth is weighted, and what the points thresholds are for each grade.
In tabs (1), (2), and (3), the upper image shows what the distribution of schools would have been in 2013 in terms of total points earned under the model parameters selected. The lower image shows a running total of how many A, B, C, D and F schools there would have been in that same scenario. Tab (4) allows you to select a specific school and see in more of a report card format how different changes selected would have effected that school's grade in 2013.
Some important notes to keep in mind as you use the visualization:
