Through the promotion of professional counselling services, Siaap has helped people achieve emotional wholeness in dealing with the consequences of HIV/AIDS. Since 1996, Siaap has helped train, place, and supervise counsellors in over 150 counselling centres and government hospitals in India.

Preventing Parent-to-Child Transmission of HIV (PPTCT) 

PPTCT centres help pre-natal mothers avoid unwanted pregnancy, prevent tranmission of HIV from mother to child, and provide support for HIV-positive mothers and children. The PPTCT design is a collaboration of UNICEF, the Tamil Nadu State AIDS Control Society, and SIAAP. SIAAP recruits, trains, and supervises counsellors for the centres.

65 PPTCT centres exist in Tamil Nadu, situated in government hospitals, medical colleges, private hospitals, and Christian missionaries
Tamil Nadu is one of only 5 states in India having PPTCT centres 98% of PPTCT centres in Tamil Nadu are fully functional, operating with group education sessions, counselling, testing services, an on-call doctor, and a pharmacy

Voluntary Counselling and Confidentiality Testing Centre (VCCTC)

The Voluntary Counselling and Confidentiality Testing Centre program was created to reduce the transmission of HIV through voluntary testing and counselling. VCCTCs provide professional, client-centred services in an easily accessible, non-threatening, confidential and non-discriminatory environment.

There are 52 VCCTCs in Tamil Nadu, the largest number in all of India

SIAAP is also on the board of the Voluntary Counselling and Testing Steering Committee, an advisory board to NACO

The Tamil Nadu State AIDS Control Society (TNSACS) commissioned SIAAP to place counsellors in all VCCTC and PPTCT centres

TNSACS attempted to mandate a minimum educational qualification for counsellors, however SIAAP protested this standard, arguing that many of their best counsellors draw from experience and not book-knowledge

SIAAP publishes the Counsellor Digest, a forum for information, debate, and testimonials written for counsellors by counsellors in HIV care.
