The assessment tool will depend on your objective but the 12 components framework will good to use considering the system thinking approach principle associated with it.  In addition, the stakeholders engagement which usually lack in most situation is a plus regarding the buy-in of end users.

Well as previously mentioned by someone, UNAIDS, WHO and global fund have guidelines which are being implemented for the monitoring and evaluation system in Pakistan.

I agree with what is suggested.  It is also good to search what is available in the Ministry of Health of Kenya since it is one of the countries where HIV research and programs started decades ago.  I would also advise you to clearly identify your focus - objectives because there are many guidelines out there.  Since most HIV and AIDS programs are supported by Global Fund, PEPFAR...it is advisable to look for guidelines that are shared by many big organizations such as The M & E toolkit for HIV, TB and malaria and health and community system strengthening. This toolkit is developed by multiple organizations with global leadership in the area: WHO, The World Bank, UNICEF, UNAIDS, USAID, MEASURE Evaluation...Most national programs operate in collaboration with the global system.
