Electrical ESE/IES Syllabus 2023


The Indian Engineering Services (IES) are the services which cater to the technical and managerial functions of the government of India in the field of engineering. Indian Engineering Services (IES) exam, also known as Engineering Services Examination (ESE), is a national level recruitment exam organized by Union Public Services Commission (UPSC). A three-stage competitive examination (preliminary, main and personality tests), the Engineering Services Examination (ESE), is conducted by the UPSC for recruitment to the Indian Engineering Services. The exam is conducted to recruit candidates for engineering posts under the Government of India.

Contents for syllabi of both the Papers together for Preliminary Examination/ Stage-I (objective type Paper–II) and separately for Main/ Stage-II Examination (Conventional type Paper-I and Paper – II).
