rse

RSE is an acronym used for several distinct concepts and organizations across fields such as education, computing, and learned societies.

In education, RSE commonly stands for Relationships and Sex Education, particularly in the United Kingdom. It denotes curricula addressing interpersonal relationships, sexual development, consent, sexuality, gender identity, and health, often integrated into personal, social, health and economic education (PSHE). Some jurisdictions require RSE as part of national standards.

In computing and software engineering, RSE can denote two roles or tools: Research Software Engineer, a professional who blends research and software engineering to build reproducible, high-quality software in research environments; and IBM's Rational Software Engineer, an Eclipse-based IDE used for developing Java and other applications; both aim to improve software quality and collaboration.

In science and public life, RSE can refer to the Royal Society of Edinburgh, the national academy of Scotland, founded in 1783 to promote science, arts, and letters; it supports fellows, grants, policy work, and public engagement.

Other uses exist in specific sectors, such as regional or organization-specific acronyms; thus the intended meaning depends on context.
