     The importance of social housing of captive NHPs to their psychological well-being has been well established, but even as late as 2007, more than half of indoor housed primates in the US were singly housed (Baker et al 2007). Our site originally group housed juveniles in indoor gang-style pens. Facility renovation and expansion increased pair and triple housing space necessitating the development of social housing strategies to fill that space. Our site has pair or triple housed greater than 1000 new sets of animals per year, with many lessons learned. The aim of this presentation is to share pairing strategies learned in the evolution of the social housing program, including methodology and temperament characteristics of successful social housing sets. A difference in success rates in pairing juveniles (100%) vs sub-adults (96-97%) vs adults (100% females, 83% males) drove the development of different processes for pairing depending on age class. The pairing process was streamlined for the first two classes, while a technique of analyzing pre-pairing behavior using a modified version of the human intruder test, and using the assessment to select particular partners, was developed for the adult males that increased the pairing success by 8%. These modifications resulted in more efficient use of labor resources and increased our level of social housing across the colony.
