IDEC National Summary Reports

Results Matter! Ongoing research and evaluation are essential LCNA’s intervention success. Since 1984, data have been collected and analyzed for each of the more than 2.5 million children served.

The International Data Evaluation Center (IDEC), an ongoing research project in the College of Education and Human Ecology at The Ohio State University, is responsible for collecting and analyzing data. Intervention teachers enter data through IDEC’s secure website for each student they serve. Teacher Leaders review and approve data then receive evaluation reports each year for each training site, school, and school district. The International Data Evaluation Center also prepares national reports, conducts academic research, collaborates with faculty at other universities on a variety of research endeavors, and assists researchers in their efforts.

The extensive IDEC database has made LCNA’s interventions accountable to schools and funding sources, and informed teaching and management decisions. An annual technical report of results is available each year and is posted on the IDEC website.
