普通教育发展证书(General Educational Development，或简称GED考试) 是为验证个人是否拥有美国或加拿大高中级别学术技能而设立的考试及证书，测试内容共包含五类科目。GED这一首字母缩写组合也时常含有“普通教育文凭”、“普通等阶文凭” 或者“毕业生等阶学位”之义。

作为美国教育委员会和培生 公司的合作项目，GED考试服务中心是GED考试的唯一运营者。该考试可以通过纸张或者电脑进行，但考试者必须亲自到场。在测验结果被审读之后，及格的测试者会被授予一份“高中等级学历证明”或者与之名称相似的凭证。GED考试与高中文凭具有同等效力。

General Educational Development (GED) tests are a group of four subject tests which, when passed, provide certification that the test taker has American or Canadian high school-level academic skills.

Although the "GED" initialism is frequently mistaken as meaning "general education degree" or "general education diploma", the American Council on Education, which owns the GED trademark, coined the initialism to identify "tests of general educational development" that measure proficiency in science, mathematics, social studies, reading, and writing. Passing the GED test gives those who do not complete high school, or who do not meet requirements for high school diploma, the opportunity to earn their high school equivalency credential, also called a high school equivalency diploma, general equivalency diploma a high-school degree awarded by a series of examinations; also called GED as in the dictionary, in the majority of the United States, Canada, or internationally. In 2014, some states in the United States switched to alternate exams, HiSET and TASC.
