Competition Commission staffing rules set pay bands, recruitment mix, qualifications, promotion, deputation, eligibility and committee composition. Schedule I sets sanctioned posts with pay bands/grade pay and prescribes, for each post, whether selection applies, age limits, essential educational and professional qualifications, probation periods, and the proportionate methods of filling vacancies by promotion, deputation (including transfer or short-term contract) and direct recruitment. It requires specified years of experience in analogous grades for deputation, limits deputation periods and age for deputation, and mandates promotion consideration by a Departmental Promotion or Selection Committee composed of the Chairperson, Members of the Commission and, where appropriate, the Director General, Secretary and co-opted outside experts.
