Episode notes
Pandemic Sparked Research Into External Actors
- Trinidad moved from a pandemic-era interest in external organizations to studying EWIs because he couldn't access schools.
- He reached out to researchers and philanthropies and became fascinated by the people building dropout-prediction systems.
Early Signals Make Dropout Prevention Possible
- Early warning indicators (EWIs) use attendance, behavior, and course performance to flag students at risk of dropping out by ninth grade.
- EWIs create dashboards that let schools intervene early with targeted supports before students fall irreversibly off track.
Twenty-Five Year Oral-Document History
- Trinidad compiled a 25-year history of EWIs by interviewing nearly 100 people and collecting over 3,000 pages of documents.
- He combined oral histories and archival materials across Chicago, Philadelphia, and New York to trace hidden actors and change over time.
