Candidates for Parliament must possess a formal university degree, while candidates for local offices need to produce be certificate of functionally literacy test to attest that they are adequately skilled. Furthermore, only candidates for the National Assembly may belong to a political party. Candidates must make public disclosures regarding professions, income, assets and liabilities, educational qualifications, and criminal record; the disclosure is reviewed by the Returning Officer. All candidates must also obtain a security clearance. For non-partisan elections, a declaration of partisan non-affiliation must also be filed. As part of their candidature, they also choose a symbol and appear on a list published by the Returning Officer.
