The sole question presented in this case concerns the propriety of a collective bargaining unit determination made by the National Labor Relations Board (Board). Kendall College (Kendall) petitions this *218 Court for review of the Board’s decision and order 1 requiring the college to bargain collectively with Kendall College Council North Suburban Teachers Union, AFT Local 1274, AFL-CIO. For the reasons set forth, we deny the petition for review and grant the Board’s cross-application for enforcement.
Kendall is a small college which offers a two-year liberal arts curriculum to students who generally transfer to four-year institutions to complete their college education. At the relevant times Kendall employed about 19 full-time and an equal number of part-time faculty members. The part-time faculty members consist of teachers employed on a “per-course” contract and those employed on a “pro-rated” full-time contract. 2
The differences between pro-rated part-time teachers and their per-course colleagues are significant. Like their full-time counterparts, pro-rated part-timers receive salaries which reflect their training and experience. These teachers are employed under contracts identical to full-time contracts, and receive the same level of compensation as full-timers, but their contracts are pro-rated to reflect the lesser number of hours they teach during the contract year. 3 Full-time faculty and pro-rated part-timers are required by contract to attend Faculty Senate meetings and to serve on its various committees. Full-time faculty also receive such fringe benefits as retirement plan, health insurance, tuition reduction for themselves and their dependents, and sabbatical leaves. Pro-rated part-timers are entitled to most of these same fringe benefits.
In contrast, the educational background and teaching experience of per-course part-time teachers have no effect on their rate of compensation. The standard compensation for a three-credit course is $720. 4 This fixed amount may be less if fewer than eight students enroll in a course, or may be slightly higher for a laboratory science course. Per-course part-timers are not required to attend the Faculty Senate meetings, but are permitted to attend if they wish. Most fringe benefits are not available to per-course part-timers. Furthermore, the record reflects that almost half of the per-course part-timers hold full-time jobs elsewhere, and many are graduate students working toward degrees.
The Board determined that an appropriate collective bargaining unit at Kendall consisted of the full-time faculty and those part-time faculty members employed on the basis of pro-rated full-time contracts. The Board excluded the per-course part-timers because it found that they did not share a community of interest with the full-time and pro-rated part-time faculty. Kendall refused to bargain, and has petitioned for review of the Board’s bargaining unit determination.

Kendall first maintains that we must “closely scrutinize” the Board’s unit determination in the instant case, since it presents for review for the first time the Board’s exclusion of part-time faculty members from a unit determination. Whatever *219 the phrase “close scrutiny” means in the context of this case, we note that the primary responsibility for determining appropriate units for collective bargaining purposes rests with the Board. See 29 U.S.C. § 159(b). We are also mindful that
“[T]he issue as to what unit is appropriate for bargaining is one for which no absolute rule of law is laid down by statute, and none should be by decision. It involves of necessity a large measure of informed discretion, and the decision of the Board, if not final, is rarely to be disturbed.”

In
C. W. Post,
Kendall contends that the New York University case and the Board’s subsequent decisions following it 5 represent completely unprecedented Board action resulting in a per se rule excluding part-time faculty members from bargaining units. Kendall then asserts that the application of the per se rule in this case constitutes an abuse of discretion which will result in a Balkanization of bargaining units and an impairment of the rights of the excluded part-timers. We do not agree.
Any contention that the Board’s New York University decision resulted in a per se principle rule of excluding part-time members from faculty bargaining units cannot be seriously asserted, for the Board in the instant case included those part-time faculty members who are employed under the terms of a full-time contract on a prorated basis. Furthermore, we fail to perceive any abuse of discretion owing to the possible results of the Board’s unit determination. Fragmentation of units and im *220 pairment of rights of excluded employees are always a necessary possibility whenever the Board determines the scope of a bargaining unit which encompasses less than all employees. The Board found that the interests of the per-course part-timers were sufficiently different from the interests of full-timers and pro-rated part-timers. Given those differences in interests, we find no abuse of discretion on the basis that the “community of interest” determination made by the Board here may result in the claimed adverse effects.
Nor do we find any merit to the assertion that the Board’s decision in this case constituted an “unprecedented exception” from the Board’s general principle of including part-time employees with their full-time counterparts. (See:
William Dimond & Co.,

On the basis of factors enumerated in
New York University, supra,
The record indicates that faculty members of the unit determined by the Board are compensated at a rate at least 20% higher than the rate of the excluded part-timers. Further, the included employees enjoy such fringe benefits as health insurance, pension plan, and sabbaticals — benefits not available to the excluded part-timers. The record further demonstrates that, although the excluded part-timers are allowed to attend the Faculty Senate, they are not contractually required to do so. Participation by per-course part-timers in faculty governance functions is thus limited in comparison to the included employees. With respect to non-teaching responsibilities, the included teachers are contractually required to counsel students and to sponsor approved student activities. Per-course teachers are contractually required to keep posted office hours and may be called upon to counsel students.
In excluding the per-course part-timers, the Regional Director noted that the interests and duties of per-course faculty members at Kendall are generally limited to teaching and grading. In contrast, the group of pro-rated part-timers consist of teachers with more substantial ties to the college. The record shows that the pro-rated part-time faculty consist of former full-time faculty members, dual-function employees performing administrative and counselling duties in addition to teaching, instructors hired to implement a new program which, if successful, will be integrated into the curriculum, and former per-course faculty who have been given a pro-rated contract in recognition of their past services and substantial connection with Kendall.
*221 On the basis of the record before us, we find substantial evidence supporting the Board’s determination than an appropriate collective bargaining unit should include full-time teachers and pro-rated part-time teachers, and should exclude per-eourse part-time employees.
Accordingly, for the reasons set forth herein, we deny Kendall’s petition for review, and grant the Board’s cross-application for enforcement.
PETITION FOR REVIEW DENIED.
CROSS-APPLICATION FOR ENFORCEMENT GRANTED.
Notes
.
Kendall College,
. Numerically, about 14 part-time teachers were employed on a per-course contract. Of the 5 part-timers employed on a pro-rated contract, several were dual function employees engaged in both teaching and other administrative duties at Kendall.
. The record shows that full-time faculty are contractually required to teach 27 hours during the academic year, maintain office hours on-campus, advise students, and sponsor student activities. The record further shows that most part-time faculty sign contracts to teach one course for one semester.
. The record shows that this rate is 20% lower than the lowest rate receivable by a pro-rated part-timer.
. See:
Catholic University,
. Only full-time faculty are eligible for tenure. Owing to a decline in enrollment in recent years, Kendall imposed a tenure moratorium. The college has no tenure track, and had no policy concerning credit for part-time teaching when the moratorium is lifted.
