All policies, guidelines and procedures in the Student and Faculty Handbook and the Board and Administrative Policy Manuals are applicable to this course

Civility Statement

Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others.

      Civility Notification Statement. If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor; it is the student’s responsibility to arrange for this conference. 

      This statement reflects step one in a possible four step process.  The Incivility Protocol is detailed in the Blinn College Student Handbook,

Attendance Policy

The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. A record of attendance will be maintained from the first day of classes and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences during the semester, he or she will be sent an e-mail by the College District requiring the student to contact his or her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two weeks’ worth of unexcused absences, he or she will be administratively withdrawn from class.

There are four forms of excused absences recognized by the institution:

  1. observance of religious holy days—The student should notify his or her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s);
  2. representing the College District at an official institutional function;
  3. high school dual credit students representing the independent school district at an official institutional function; and
  4. military service.

Other absences may be considered excused at the discretion of the faculty

member with appropriate documentation.  A student enrolled in a developmental course is subject to College District-mandated attendance policies. Failure to attend developmental classes shall result in removal from the course as defined by the College District.

It is the student’s responsibility to officially drop a class he or she is no longer attending.  To officially drop a class the student must obtain the class withdrawal form from Enrollment Services, complete the class withdrawal form, secure the required signatures, and return the completed form to Enrollment Services. The last day to drop with a Q is according to the Academic Calendar.

Scholastic Integrity

Blinn College does not tolerate cheating, plagiarism, or any other act of dishonesty with regard to the course in which you are enrolled.  The following text defines the faculty member’s responsibility with regard to the scholastic integrity expectation for this and all courses at Blinn College.

It is the responsibility of faculty members to maintain scholastic integrity at the College District by refusing to tolerate any form of scholastic dishonesty.  Adequate control of test materials, strict supervision during testing, and other preventive measures should be utilized, as necessary, to prevent cheating or plagiarism.  If there is compelling evidence that a student is involved in cheating or plagiarism, the instructor should assume responsibility and address the infraction.  Likewise, any student accused of scholastic dishonesty is entitled to due process as outlined in Blinn College Board Policy FLB (Local).  The Scholastic Integrity Policy is located in the Blinn College Student Handbook,  In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.

Blinn College is dedicated to providing the least restrictive learning environment for all students. Support services for students with documented disabilities are provided on an individual basis, upon request. Requests for services should be made directly to the Office of Special Populations serving the campus of your choice.  For the Bryan campus, the Office of Special Populations (Administration Building) can be reached at (979)209-7251.  The Brenham, Sealy and Schulenburg campuses are served by the Office of Special Populations on the Brenham campus (Administration Building Room 104) and can be reached at (979)830-4157.  Additional information can be found at

Final Grade Appeal

If a student wishes to appeal a final grade in a course, Blinn College Board Policy FLDB (Local), Course Grade Complaints, outlines the timeline for the appeal and the four steps in the appeal.  This policy is located in the Blinn College Student Handbook,

Course Policies


Attendance Policy Reminder:  Missing lecture, lab or both will count as one absence.  For classes that meet twice a week during the spring semester two absences counts as one week's absence.  Students accumulating two week’s worth of absences (four unexcused absences) will be dropped.

Any student requesting an excused absence must email the professor before noon on the following day explaining why the absence should be excused. In cases where sending an email is not possible a phone call is required.
