The West African International Summer School for Young Astronomers (WAISSYA) is a week-long program for university science students and teachers from West Africa to develop their interest in astronomy. The first summer school was held in Abuja, Nigeria, in 2013; the second Summer School was held in Nsukka, Nigeria, in July 2015. West Africa has a large number of students interested in science, but a paucity of facilities or interest from funding bodies in developing West African astronomy. Our broad goals for the WAISSYA program are: (1) to introduce West African students to astronomy; (2) to exchange ideas about teaching and learning in West Africa and abroad; and (3) to continue building a sustained astronomy partnership between West Africa and Canada. We now briefly describe three defining aspects of WAISSYA 2015.
