1. ITM-IDM DAT (Design Aptitude Test)
   - IDM's own institutional exam 
   - Tests creative ability, design thinking, GK, etc.

2. UCEED (Undergraduate Common Entrance Exam for Design)
   - National level test for admission to design programs
   - Conducted by IIT Bombay

   - By National Institute of Design
   - Evaluates observation, drawing, creativity skills

4. NIFT Entrance Exam

So in summary, ITM-IDM shortlists and admits candidates based on valid scores in any one of the four - ITM-IDM DAT, UCEED, NID DAT or NIFT entrance exams along with performance in portfolio review and interview rounds.

It is difficult to objectively state that ITM Institute of Design and Media (IDM), Andheri West is the 'best' design institute in Mumbai. However, here is an evaluation of ITM-IDM based on certain parameters:

1. Programs Offered: ITM-IDM offers a diverse set of UG and PG level design programs including B.Des, M.Des, Integrated Program in Design, Design Specialisation courses etc. This provides students a good range of study options.

2. Faculty and Facilities: The institute has credentialed faculty from leading design schools. The campus is equipped with design studios, labs, auditoriums and other amenities. However, it is relatively smaller compared to bigger design institutes.  

3. Industry Exposure: ITM-IDM has extensive industry collaborations which offers good internship and placement opportunities to students during and after the program.

4. ROI and Cost: In terms of fees and placements, ITM-IDM offers a reasonably good return-on-investment compared to education quality. But fees are higher compared to government design institutes.

In summary - While ITM-IDM is considered amongst the leading private design schools in Mumbai and offers quality design education, it faces tough competition from the likes of DSK Supinfocom, Rachana Sansad and more established government institutes like IDC IIT Bombay, DJSCE in certain parameters. An objective comparison across all such institutes is difficult to benchmark it as 'the best'.
