Tools and organization
Calculators for percent, rate of improvement, and trend, plus data privacy, binders, and routines for teams.
Three calculators
They run in your browser. Nothing you type is sent or saved. Each one is explained in a guide, with a worked example.
Runs in your browser. Nothing you type is sent or saved. The range uses the Wilson score interval, a common way to show how uncertain a percent from few trials is. It is a rough guide, not a verdict.
Explained in percent accuracy vs trials vs duration.
Runs in your browser. Nothing is sent or saved. Rate of improvement here is the gain per week: (current score minus baseline) divided by weeks between the two. Use the same measure and the same level of material for both scores.
Explained in rate of improvement explained.
Runs in your browser. Nothing is sent or saved. Enter three or more scores in time order, evenly spaced. The trendline is an ordinary least squares line through the points. Compare it with the aimline, the straight line from baseline to goal. A slope is a summary of the points, not a decision.
Explained in aimline and trendline explained.
Guides on organizing the data
A Sample IEP Data Binder Layout That Stays Current
A tab-by-tab IEP data binder or folder layout with a one-page goal card, a data log, a graph, and report copies, plus an upkeep routine and privacy notes.
A Weekly Data Routine for a Special Education Caseload
A model week for collecting, graphing, and reviewing IEP data for a caseload, with a time budget, a review cycle, and what to do when a week falls apart.
Data Privacy for IEP Records and Data Sheets
What IDEA's confidentiality rules and FERPA's education record definition mean for teacher data sheets, graphs, and files, with habits for storing them.
Small Group Data Tracking Without Losing the Individual
Collect and track IEP data in small groups: which probes can be given to a group, a grid for four students, and why each goal still needs its own graph.
