The UPSC Assistant Town Planner exam is a central government recruitment exam conducted by the Union Public Service Commission to fill positions in the Ministry of Housing and Urban Affairs and related central government organisations. Selected candidates work on urban planning projects, master plan preparation, and implementation of schemes like AMRUT (covering 500 cities with investment of Rs. 1 lakh crore) and Smart Cities Mission. The role involves GIS-based planning, zoning, and urban infrastructure development. The exam is held as vacancies arise and draws highly qualified candidates with planning or architecture degrees.

The exam typically consists of 100 objective-type questions to be answered in 120 minutes, covering Town Planning and Architecture, Urban Infrastructure, General Studies, and Reasoning and Aptitude. There is negative marking of 0.33 marks for each wrong answer. Shortlisted candidates may be called for an interview as part of the final selection process. The exact pattern may vary based on the notification, so candidates should always refer to the official UPSC advertisement for the most current details.

Urban planning sections cover master plan preparation and zoning regulations, land use planning, housing policies including PMAY Urban (1.12 crore houses sanctioned), transportation planning, environmental planning, urban renewal, and planning legislation. Knowledge of AMRUT scheme objectives (water supply and sewerage infrastructure for 500 cities), Smart Cities Mission, and national urban policies is essential. Candidates should also study GIS applications, urban economics, and planning standards such as FAR/FSI norms and population density standards.

The UPSC Assistant Town Planner is a central government post under the Ministry of Housing and Urban Affairs, focusing on national-level policy implementation and centrally sponsored schemes. State-level posts such as those in DDA, TCPO, or state urban development authorities focus on local and regional planning within specific jurisdictions. The UPSC role often involves more policy, coordination, and monitoring work, whereas state roles may involve more field-level plan preparation and regulation enforcement.

Key resources include Ballaney's "Town Planning" for foundational concepts, H.R. Kamdar for planning laws, and standard GIS textbooks. Candidates should thoroughly study the National Urban Policy 2006, URDPFI guidelines, Model Building Bye-Laws, RERA Act, and relevant notifications from MoHUA. Current affairs on urban development schemes and programmes are crucial. Solving previous GATE AR papers also helps, as the technical content is similar. Joining a dedicated coaching programme for urban planning government exams is advisable.
