A bill for an act relating to sex and gender, including those and related terms for purposes of statutory construction, indications of a person’s sex on certain vital records, gender identity under the Iowa civil rights Act, and school curricula related to gender theory. Effective date: 07/01/2025.
SF 418 makes broad changes to Iowa law to define sex and gender terms in statute as biological sex, with sex described as male or female as observed or clinically verified at birth. It also defines related family terms such as woman, man, mother, and father in biological-sex terms, states that “gender” should be treated as a synonym for sex in certain statutory contexts, and provides that “equal” does not mean same or identical. The bill further declares that separate accommodations are not inherently unequal and expressly recognizes legal protections for people with medically verifiable disorders or differences of sex development under disability law.
The bill revises vital records rules to require sex designation on birth certificates, extend filing deadlines when sex cannot be determined at birth, and require amended birth certificates to retain the sex designation at birth. It also changes several civil rights and education provisions by keeping existing protections against discrimination based on sex, sexual orientation, gender identity, and other categories, while adding language that permits sex-separated facilities and accommodations in contexts such as prisons, shelters, restrooms, locker rooms, and schools when tied to health, safety, or privacy. In education, it bars K-6 instruction, curricula, tests, surveys, or other materials relating to gender identity theory or sexual orientation, and it updates charter school and innovation zone school requirements to match those restrictions.
The bill’s impact on state law is substantial because it amends multiple chapters of the Iowa Code, including statutory construction, vital records, civil rights, housing, employment, education, and school governance. It narrows how state law interprets sex and gender, changes how state and local agencies collect and report sex data, and requires certain public records and school-related documents to use male/female classifications. It also preserves many anti-discrimination provisions while clarifying exceptions for religious institutions and sex-based separation in certain settings.
Overall sentiment in the recorded votes appears mixed but ultimately favorable to the bill’s passage. The Senate Judiciary Committee advanced it on a 14-6 vote, several proposed amendments failed by wide margins, and the bill then passed the Senate 33-14 before later passing the House 60-36. That pattern suggests the bill had strong support among Republican majorities and significant opposition from Democrats and others concerned about its scope.
The main points of contention are the bill’s treatment of gender identity, its definition of sex as strictly biological, and its restrictions on school instruction about gender identity and sexual orientation in early grades. Supporters appear to view the bill as a clarification of legal definitions, protection of privacy and safety, and a way to standardize records and school policy. Opponents likely object to the rollback or narrowing of gender-identity recognition, the limits on classroom discussion, and the potential effects on transgender and gender-nonconforming people in schools, workplaces, housing, and public accommodations.
SF 418 amends numerous Iowa Code provisions to define sex and related terms in biological terms, require sex designations on birth records, preserve birth-sex information on amended certificates, and direct state and local entities to classify collected data as male or female. It also revises the Iowa Civil Rights Act and related housing, employment, public accommodations, and education provisions to retain anti-discrimination protections while clarifying sex-based distinctions and religious exceptions, and it prohibits K-6 instruction on gender identity theory and sexual orientation.
The bill appears to have been supported by a legislative majority, with committee approval and final passage in both chambers, but opposed by a substantial minority. Failed amendment votes and the final vote margins indicate that the measure was politically divisive, with supporters framing it as a clarification of law and opponents resisting its restrictions on gender identity and school instruction.
The most notable disputes concern whether the bill improperly redefines sex and gender in a way that excludes gender identity, and whether it goes too far in limiting school curricula and instruction about gender identity and sexual orientation in kindergarten through grade six. Additional contention centers on the bill’s effects on transgender people, the use of sex-separated facilities in sensitive settings, and the balance between anti-discrimination protections and religious or privacy-based exemptions.
