The selection process for the ASO position is divided into three distinct stages, with candidates required to successfully complete each stage to progress to the next.
Stage 1 - Objective Papers
Candidates will sit for Paper I, which encompasses General Awareness and English Language and Comprehension, along with Paper II that covers General Intelligence, Reasoning, and Mental Ability. Both papers are objective-type with negative marking implemented.
Stage 2 - Descriptive Paper
Successful candidates from Stage 1 will then attempt Paper III, which is a descriptive assessment in English or Hindi. This paper includes tasks such as essay writing, précis writing, and the crafting of letters or applications.
Stage 3 - Computer Proficiency Test (CPT)

The final merit list is compiled solely from the objective and descriptive performance, with the CPT serving purely as a qualifying measure.
