FAUGHN Institutional Policies TH STUDENT RESPONSIBILITIES: A. Attendance: Effective Spring Term 2010, student absences will be recorded from the first day the class meets. Regular and punctual attendance in all classes and laboratories, day and evening, is required. Students who are absent for any reason should always consult with their instructors. Course syllabi must provide specific information regarding attendance, including, for courses involving the internet, online activity that constitutes attendance. Also, both tardiness and early departure from class may be considered forms of absenteeism. In all cases, students will be held responsible for completion of course requirements covered in their absence. Additionally, it is the student s responsibility to drop a course for nonattendance. Course instructors establish policy with regard to attendance in their respective syllabi and may drop a student for excessive absences. Absences are considered excessive when more than 12.5 percent of the total contact hours of instruction in a semester, including lecture and lab, are missed. For example, in a threecredit-hour lecture class, students may be dropped after more than six contact hours of absences. In a four-credit-hour lecture/lab class, students may be dropped after more than eight contact hours of absences. Absences are counted regardless of whether they occur consecutively. In special programs with additional accreditation or certification standards, additional attendance requirements may be enforced but faculty must clearly explain these policies in their syllabi. Students who stop attending class for any reason should contact the instructor and the college registrar to officially withdraw from the class. Students may be required to consult with an advisor or designee before dropping. Failure to officially withdraw may result in a failing grade for the course. It is the student s responsibility to withdraw officially from a class by submitting a completed Withdrawal Form to the Admissions and Records Office. B. Student Responsibility for Success (Alamo Colleges Policy F.6.2): As members of the Alamo Colleges learning community, students, faculty, staff and administrators all share the responsibility to create an atmosphere where knowledge, integrity, truth, and academic honesty are valued and expected. A clear acknowledgment of the mutual obligations of all members of the academic community emphasizes this implicit partnership in fostering the conditions necessary for student success. In this relationship, the Alamo Colleges provides institutional policies, procedures, and opportunities to facilitate student learning that encourage interaction, involvement and responsible participation. Inherent in the academic climate is the expectation that students will assume responsibility for contributing to their own development and learning.

Textbook Availability A student of this institution is not under any obligation to purchase a textbook from a university-affiliated bookstore. The same textbook may also be available from an independent retailer, including an online retailer. COLLEGE REQUIREMENTS: A comprehensive final evaluation, not to exceed three hours in length, shall be given at the end of each course at the official scheduled final exam time. Any exceptions to this requirement must be approved by the appropriate Dean. Other evaluations are given at the discretion of the instructor. A student who must be absent from a final evaluation should petition that instructor for permission to postpone the evaluation. A student absent without permission from a final evaluation is graded "0" on the exam. Incomplete Grades. The conditional grade of I may be issued to a student having a passing average on all completed coursework but for a justified reason, such as illness or death in the family or by providential hindrance, has been prevented from taking the final 11 of 12

12 examination or completing other required coursework. The I becomes an F in one hundred twenty (120) calendar days from the end of the term unless the student completes the balance of the coursework with a performance grade of D or higher. Re-enrollment in the course will not resolve the I. The student and faculty must fill out an Incomplete Contract, clearly defining the work remaining to be finished.
