Homologation (Greek homologeo, ὁμολογέω, "to agree") is the granting of approval by an official  authority. This may be a court of law, a government department, or an academic or professional body, any of which would normally work from a set of strict rules or standards to determine whether such approval should be given. The word may be considered very roughly synonymous with , and in fact in French and Spanish may be used with regard to academic degrees (see apostille). Certification is another possible synonym, while to homologate is the infinitive verb form.
