College ROI Data — what U.S. colleges and majors actually pay back
Clean, citable tables on the lifetime financial return of U.S. colleges and majors —
30-year net present value by school and state, ROI by major category, the out-of-state
premium, and how exposed each major's career paths are to today's AI. Maintained by
LE TEEN, a college-ROI data project. Every number traces to a
public source; nothing is scraped, modeled behind closed doors, or vibes.

Dataset Summary
We introduce a Romanian IT Dataset (RoITD) resembling SQuAD 1.1. RoITD consists of 9575 Romanian QA pairs formulated by crowd workers. QA pairs are based on 5043 articles from Romanian Wikipedia articles describing IT and household products. Of the total number of questions, 5103 are possible (i.e. the correct answer can be found within the paragraph) and 4472 are not possible (i.e. the given answer is a "plausible answer" and not correct)
