The Administrative Reforms Commission has primarily published two reports known as the ARC Reports. You must study both reports thoroughly as a UPSC aspirant, and this is because the topic of ARC reports holds immense value in the UPSC syllabus.
However, if you have less time for UPSC preparation, you must focus on the second report. The 2nd ARC Report puts forth some critical recommendations for the public administrative system. It is split into 15 divisions dedicated to topics that include:
Right to Information (RTI)
Unlocking Human Capital
Disaster management
Ethics in Governance
Combating terrorism
Social Capital
E-Governance
Financial Management
