PARTIAL is upheld. The underlying 2014 promise is verbatim-confirmed: PolitiFact (2014) documents Ernst calling in the April 24, 2014 primary debate for "closing the doors to the Department of Education at the federal level" and stating "our children are better educated when it's coming from the state" — an exact match for the promise text. Outcome as of mid-2026: the department still exists (abolition requires an act of Congress; no floor vote on abolition has occurred). But Ernst took concrete, completed action advancing the goal: on March 3, 2025 she voted Yea (Senate Roll Call Vote 99, 51-45, "Nomination Confirmed") to confirm Linda McMahon as Education Secretary, whose explicit Trump mandate was to wind the department down ("put yourself out of a job"), and she publicly backed the administration's dismantling effort in 2025. That is real action advancing the promise — hence not IGNORED, ABSTAINED, or UNRATABLE. It falls short of FULL (department not closed) and CHAMPIONED (she did not sponsor/cosponsor the leading 2025 Senate abolition bills S.1148 or S.1402 and did not lead the legislative push). ATTEMPTED overstates her role since she did not force a failed floor vote on abolition itself. PARTIAL is the best fit and is not overstated. Confidence 0.6 reflects the moderate PARTIAL/NO_OPPORTUNITY boundary (no direct abolition vote reached the floor).
