The specific licenses and certifications required for practicing architecture vary by country and by individual jurisdiction within each country. In general, however, most countries require architects to hold a professional degree in architecture, such as a Bachelor of Architecture (B.Arch) or Master of Architecture (M.Arch), from a program that is accredited by the relevant national architecture accrediting body.
Additionally, most countries also require architects to pass a licensure examination, which typically includes both a written and a practical component. In some cases, architects may also be required to complete a certain number of hours of continuing education in order to maintain their license.
In the United States, for example, architects must hold a professional degree in architecture from an accredited program, pass the Architect Registration Examination (ARE), and meet the requirements for continuing education in order to be licensed to practice architecture in any of the 50 states.
It is important to research the specific licensing requirements in your country and jurisdiction in order to ensure that you are able to practice architecture legally and ethically. You can typically find this information on the website of your national or local architecture association or regulatory body.
