This article describes a case study in which Our Lady of Hungary Catholic School (OLH) principal Kevin Goralczyk and the parish's pastor, Reverend Kevin Bauman, faced educators' universal challenge: Knowing what students need to learn but wondering how to evaluate if they were really successfully taking in the information rather than simply studying for tests. The pastor already knew NWEA™ assessments had a solid track record in helping educators close achievement gaps and push high achievers; Goralczyk found the organization's professional learning (PL) well-suited to helping the school become a more collaborative and academically successful community. The school saw signifcant changes during their first year using MAP® Growth™ and Children's Progress Academic Assessment™ (CPAA™), an early learning skills assessment, as well as NWEA PL focused on classroom formative assessment strategies. Student growth accelerated, teachers' skills strengthened, and students became more engaged with their personal learning journeys.
