As a Hillel employee, you will be hearing these two words often. I personally hope I never have to hear them again, unless I work for a Hillel in the future.
Engagement Students:
Engagement students are the primary target audience for the JCSC. These are the students who won't actively seek out a Hillel program, and they probably have no desire to enter the building. They are not involved in Jewish life on campus. The only exception is that during the high holidays, Hillel attracts many engagement students who would never come otherwise. As the JCSC, it is your job to engage the students, and help them to form their own Jewish identity through your interaction with them. Hopefully, you will get them to meet other Jewish students with similar interests in a comfortable environment. I don't try to get the students to come to Hillel. I go onto campus, and I hang out with them in Residence halls, coffee shops, the University Center, the quads, and the gym. The key is being friendly and available. You don't want to appear as a bible salesman who is pushing religion. There are many Jews at Tulane, but most don't want to be hassled religiously.
Empowerment Students:
Empowerment students are much more comfortable with their Jewish identity, and they will actively participate in Jewish life on campus. Traditionally, members of the Student Board would be considered empowerment students. Students who come to Hillel for Friday night services, or students who come to dinner every Tuesday night are probably empowered. Next year the Student Board is being restructured, and the roles and responsibilities of the JCSC and the JSLC will be a little different than this year.
