The NCSEAM Improvement Calculator was developed as a tool for states that are using the NCSEAM Parent/Family Surveys to use in setting targets for the Part B parent involvement indicator (Indicator #8) and/or the Part C family outcomes indicator (Indicator #4). Setting a measurable and rigorous target on these indicators involves determining, first, what amount of change indicates real improvement, and not just random variation owing to sampling and measurement error. The NCSEAM Improvement Calculator accomplishes this. Setting a measurable and rigorous target also involves determining what amount of change represents a meaningful improvement in results for children and families. This is a matter of judgment to be determined by each state.
