Graduate students, by definition, are enrolled in a course of study at a university to earn a degree that will further qualify them for professional employment. Although one could presumably find a well-paying and satisfying job with a bachelor's degree, graduate students share the hope that a master's or doctoral degree will lead to increased salary and status, flexibility in work projects, and the opportunity to study a topic in depth. Some people switch disciplines between their undergraduate and graduate studies. Of course, there are sometimes more self-serving reasons for going to graduate school, such as delaying the inevitable job search and entrance into the "real world", continuing to be near college friends or in the college environment, and parental/professor/peer pressure (good grades = readiness for graduate school).
Whatever the reason, graduate students are stuck between a rock and a hard place. They're not undergraduate students any more; that piece of sheepskin is certainly well-earned and somehow that intervening summer completely changes a new graduate student's attitude towards undergraduates. However, graduate students aren't truly young professionals either, mostly because their salaries are too low. At least, this is true at major research universities like UC Berkeley or MIT, where the majority of graduate students focus full-time on their studies during the course of their degrees, even if officially they are supported by a "teaching assistantship" or "research assistantship" mandating only 20 hours of work per week. I rarely heard of anyone at MIT holding down an additional outside full-time or part-time job. This is not the case among the several graduate students I've met in DC, many of whom do work full- or part-time in addition to completing their masters' degrees. Perhaps, in non-science masters' programs, there is not adequate financial support for students, necessitating salaried work in order to not be in massive debt upon graduation. There is also the notable fact that the majority of MIT graduate students live on-campus or very close to campus, making the campus community quite close-knit.
So, are graduate students then best served by specific on-campus graduate Christian ministries, church young professionals' ministries, or non-specific church-wide ministries? For a specific example, MIT has a Graduate Christian Fellowship affiliated with Intervarsity Christian Fellowship, of which I was an active member/leader during my years in graduate school. Park Street Church has a Café ministry to young professionals in their 20's. GCF and Café had many activities in common, including large group worship/fellowship meetings, small group Bible studies, prayer meetings, and service projects. Park Street Church itself had neighborhood small groups, adult education (aka Sunday School), Cityworks urban outreach, choir, soli deo gloria (arts ministry), among others. How should an MIT graduate student choose between these all? I'm not even mentioning the smorgasboard of activities found at other churches in the Boston/Cambridge area.
Since I've been out of graduate school for a year and a half now, I can confidently assert that graduate students need on-campus small group Bible studies, or at least regular meetings with other graduate students. These peer-group Bible studies are vital not because graduate students study the Bible better with other intellectuals. Rather, the graduate school experience is long, difficult, and discouraging, and nobody understands this better than one's peers who are also undergoing the same long, difficult, and discouraging indenture. This shared understanding is the key to effective prayer support and encouragement. Of course, this also involves one-on-one discipleship and leadership training for the small group discussion facilitators.
The other unique aspect of graduate student ministries is the integration of faith and work. Nowhere else does one think critically about how the Christian faith is not separate from, or incompatible with, the academic calling, whether it be in natural/physical sciences, technology, law, business, humanities, social sciences, etc. Rather, one's Christian faith should encompass all of daily life, not just church on Sundays and Bible study on Wednesdays. I definitely miss thinking and dialoguing about the ethical Christian implications of copyright law, or what science is actually present/not present in the Bible, or how my "secular" scientific research is actually related to God's creation, or how to share my faith in the workplace without fear of repercussion.
Most graduate students I've known at MIT have complained that they are not involved in church at all, and the only people they know at church are other MIT people. My solution to this dilemma is to keep the MIT-specific small group Bible studies, and have monthly lectures by Christian MIT professors on how they've personally tied in their faith and academic work. Perhaps there should also be a regular discussion group on responsible technology. Other than that, graduate students should be actively involved in adult education, service projects, and arts/music ministries through their local churches, and seek out opportunities to fellowship and pray with the church-wide body of believers.
