Executive Summary
This quasi-experimental study examined the relationship between educators’ access to Goalbook Toolkit and special educator retention in North Carolina — both in the same district and anywhere in the state’s public schools. Using statewide data from 2012–13 to 2022–23, researchers applied an event-study model comparing four Goalbook adopting districts to their own pre-adoption baselines and to nine similar comparison districts, with controls that separate the special-educator effect from general teacher retention.
A statistically significant gain was evident for novice educators (five or fewer years)with access to Goalbook Toolkit: a 9.1-percentage-point increase in district retention and 8.2 percentage points statewide. Excluding the pandemic years, the district gain rose to 11.2 percentage points.
The Methodology
This impact study focused on Goalbook Toolkit usage and special educator retention in North Carolina. Because state data does not label teachers by subject, researchers identified special educators through fiscal codes — classifying those who drew at least 50% of gross pay from special education activities.
Special educator retention was measured two ways: Employment in the same district, and anywhere in NC public schools, the following year. A Callaway & Sant’Anna (2021) event-study estimator handled the staggered district adoption, with covariates for school level, Title I, % of free/reduced lunch, minority enrollment, and baseline achievement, plus general education teacher retention.

From Research To Practice: Implications for Leadership, Teaching, and Learning
Retention gains concentrated exactly where turnover is most costly — the earliest, hardest career years — suggesting Goalbook Toolkit helps new special educators survive the transition into the profession. For districts fighting a chronic special educator shortage (turnover runs ~25% higher than general education), that continuity is both a service-quality and a cost lever. The effect is strongest when Goalbook Toolkit is embedded in induction and mentoring rather than offered as a standalone resource.
