How Someone Becomes an SDM
The pathway to this office varies state to state but two upper-level routes stand out:
Route 1: State Public Service Commission (State PCS)
Usually in most of the states SDMs are recruited through state’s own civil service exam conducted by Public Service Commission of that particular state. Examples include:
- UP for UPPSC (Uttar Pradesh Public Service Commission)
- Bihar Public Service Commission (BPSC) for the State of Bihar
- For MP: MPPSC (Madhya Pradesh Public Service Commission)
- Rajasthan Public Service Commission (RPSC) for, Rajasthan
- Haryana HPSC (Haryana Public Service Commission)
All State PCS exams have 3 stages, which are a preliminary exam, a main exam and an interview round. Candidates who score enough to be in the state civil service list are allotted to posts such as SDM, Deputy SP or Block Development Officer – based on rank and available vacancies.
Route 2: Promotion from Tehsildar
A serving Tehsildar in most of the states with a minimum qualifying service period generally ranging from 8 to 15 years is eligible for promotion to SDM via a departmental promotion committee. This model promotes officers with considerable experience into vacancies but creates a separate, less-experienced cadre from the directly recruited officers.
Route 3: IAS Officer Probation Adventure
During their probation period, usually the first two to three years of service, officers who have cleared the UPSC Civil Services Examination and been recruited to the Indian Administrative Service (IAS) are posted as Sub-Divisional Magistrates so they can gain field experience before taking on more senior roles at the district and state levels.
