Certification or Licensing
Hinduism is a highly decentralized religion, and there is no standard certification or licensing for archakas. Some U.S.-based temples may require that job applicants possess certification in specific Hindu traditions from Indian government agencies or India-based Hindu religious organizations.
Other Requirements
Some temples may require a background check. Traditionally, only those from the Brahmin caste could serve as archakas, but today individuals from any caste may do so with the requisite training if the temple rules, or Agama Shastras, permit it.
