This report represents the final results of an evaluation of Project EQuIPD--Engaging Quality Instruction through Professional Development. The project provided two years of intensive professional development to help teachers learn to think more strategically about how to improve student outcomes using technology-based inquiry instruction. The project also prepared participating teachers to train their colleagues. Led by the University of Florida, Project EQuIPD was a three-year grant awarded through the U.S. Department of Education's Supporting Effective Educator Development (SEED) Program. The project was implemented in 121 schools in ten counties in Florida. The impact of the project was studied with a randomized controlled trial. Key findings from the evaluation include: (1) The program was able to implement all intended activities, modifying some of the delivery methods in response to the COVID-19 pandemic; (2) On a survey, treatment teachers reported statistically significantly higher levels of knowledge and higher implementation of EQuIPD instructional practices than control teacher; (3) Observations of teachers' instruction showed no statistically significant overall differences between treatment and control teachers, although treatment teachers scored higher on implementation of inquiry practices than control teachers; (4) There was no significant difference in teacher retention or overall attendance between the treatment and control groups; and (5) There were no differences between treatment and control groups on overall measures of student achievement. The COVID-19 pandemic likely impacted the project's impacts and it is possible that results would have been different if the context had been different. [For the summary report, see ED626193.]
