Scores cluster high, so position within the catalogue is often more telling than the number alone.
Transferability / replicability2/3
Constitutional parity is part of a documented Latin American wave (Mexico joins Bolivia, Costa Rica, Ecuador among others), though no source confirms direct replication citing Mexico specifically.
Impact on gender equality1/1
IPU Parline data show real, measured shifts in seat composition (48.6% Chamber, 50.8% Senate in 2018).
Effectiveness1/1
The reform's stated aim — parity in Congress — was achieved and sustained across the 2018 and 2021 cycles per IPU and Washington Post reporting.
Efficiency0/1
No cost-effectiveness or implementation-cost evaluation was located in the sources reviewed.
Evaluated outcomes1/1
Outcomes are tracked cycle-over-cycle by IPU Parline and covered in peer press (Washington Post), constituting ongoing external evaluation.
Sustainability1/1
The rule is constitutional (not a program dependent on funding) and has held across two subsequent electoral cycles.
Achievement / evidence1/1
Before/after seat counts are independently documented (IPU Parline) rather than self-reported.
Gender-mainstreaming embedding1/1
Parity is embedded across all three branches and all levels of government, not limited to one body or program.
Curator validation1/1
Cross-checked against IPU Parline, DOF official gazette and Washington Post reporting — two or more independent domains.
