To understand, why the UPSC has not included the syllabus in the notification, we need to understand the methodology of UPSC to conduct Recruitment Exams (RTs).

How UPSC conducts Recruitment Exams(RTs) ?

First, the UPSC comes out with the notification with vacancy details, eligibility, number of posts etc. Then the candidates apply on the UPSC ORA portal. Then the UPSC checks, how many candidates have applied for the post. If the number of applications is in the few hundreds, then direct interviews are conducted without any written exam.

But, if the number of applicants is large, the UPSC decides to conduct the written exam. How large is this threshold number? As we understand from previous exams, even if this number is above 500, you can expect a written exam.

The same process was followed by the UPSC, when it conducted last exam of the Administrative Officer for GSI exam in year 2018. The notification for Admin Officer GSI came out in April 2018. The last date of application was 14 April 2018. The notification did not have any details of the syllabus. Then the UPSC came out with another notification in the month of July 2018. This new notification had 2 things (i) Exam date of 23 Sep 2018 and (ii) Syllabus for the exam. You may check out this notification also.

Thus for this exam also, the UPSC will come out with another notification around 1-2 months before the exam date.
