Student Growth Playground
How to Use This Growth Playground
This interactive tool lets you explore how different BOY–EOY growth models work. It is designed for practice and understanding only — please do not enter real student names or identifiable information.
1. Select a Growth Model
Use the dropdown at the top of the tool to choose a growth model such as:
-
Graduated (Points or Percent)
-
Common % Flat Growth
-
Gap Closure (Half-the-Gap)
-
Quartile/Quintile
-
District-Based Growth
The model you choose determines how growth targets are calculated.
3. Review Categories, Targets, and Results
The tool automatically shows:
-
The growth Category or Quartile for each student
-
The Target Score under the selected model
-
Whether the student Met Growth (“Yes/No”)
5. Clear or Load Example Data Anytime
Use the buttons at the top to:
-
Clear all entries
-
Load sample data to see how the model behaves with a full class
2. Enter Sample BOY and EOY Scores
Type in non-student BOY (Pre-test) and EOY (Post-test) percentages for any row.
Leave unused rows blank.
4. Try Different Scenarios
You can adjust:
-
Growth percentages
-
Gap-closure settings
-
District average growth targets
-
Quartile expectations
This helps you see how changes in BOY, EOY, or district rules affect growth outcomes.
BOY–EOY Growth Playground
This interactive tool lets you explore how different BOY–EOY growth models set expectations for student growth. Enter sample data only (no real student names or IDs). Use the dropdown to change the growth model and adjust parameters. All results are for learning and planning only and do not represent an official TIA determination.
Model parameters
You may adjust these values to simulate your district’s rules. Percentages are entered as whole numbers (for example, 20 for 20%).
Student growth entries
Enter BOY and EOY values as percentages from 0 to 100 (for example, 42 or 68.5). Leave cells blank for rows you are not using. “Met Growth?” is based on the selected model and the target score.
| # | Student (sample name) | Pre-test % (BOY) | Post-test % (EOY) | Category / Quartile | Target % | Met Growth? |

Accessibility: All inputs are keyboard-accessible and results are displayed as text (for example, “Yes” / “No”) in addition to any color cues. This tool does not store or transmit any data entered by users.
