ATTENDANCE POLICY FOR FACE-TO-FACE COURSES
A primary component of OSUIT's Mission is “to prepare and sustain a diverse student body as competitive members of a world-class workforce.” Regular and consistent attendance not only aids in academic success, dependable attendance is a requirement in today's real-world employment; therefore, regular and consistent attendance is a requirement in all OSUIT courses.
Definitions: Absent: Failing to attend all or a significant portion of a class or lab session.
A. Students may not be marked as absent if missing class for situations such as, but not limited to
1. participating in a required university activity such as a field trip;
2. fulfilling a military obligation;
3. a mandatory court appearance;
4. death in the immediate family;
5. Extreme illness or accident to oneself or immediate family. Instructors, at their discretion, may require proof of such events.
B. It is the responsibility of the student to contact and inform the instructor and/or department in advance of such excused absences whenever possible.
Tardy: Arriving late to class as defined by the individual class instructor. Faculty, at their discretion, may equate three tardies to equal one absence.
Procedures:
Early Intervention
A. Any student who misses 10% of an individual course (or earlier at faculty discretion) during a regular fifteen-week semester, or the equivalent portion of time in a shorter session, will have their name submitted by that course instructor to the OSUIT Early Alert System for retention intervention.
B. At the point the Early Alert is issued, the student must meet with their assigned faculty advisor or designated faculty/staff member within seven (7) academic calendar days for counseling on how to improve their attendance and academic success.
Excessive Absences
A. The University reserves the right to administratively withdraw any student from an individual course who misses 20% of that course, whether excused or unexcused, and, in the opinion of the instructor, the student does not have a reasonable opportunity to be successful in the course.
B. Students should be aware any of the following may impact their financial aid:
1. being administratively withdrawn from a course
2. dropping a course
3. their last date of attendance in a course

AIR CONDITIONING AND REFRIGERATION DEPARTMENT
STUDENT DRESS CODE
The primary purpose of the Air Conditioning and Refrigeration Department is to prepare students for employment. In this endeavor, one of the areas of training involves suitable attire for future technicians.
In reference to the dress code for Air Conditioning and Refrigeration students the following rules and regulations will apply:
1. Shorts, cuts-offs, sweat pants, sleeveless shirts or tank tops may not be worn in the classrooms or labs. For safety purposes, shirt tails (except jacket type) will be worn inside trousers.
2. Clothing, head gear or accessories with suggestive lettering, obscene pictures or unpatriotic displays may not be worn, anytime, in the Air Conditioning & Refrigeration Department.
NOTE: FACULTY WILL DETERMINE WHEN GUIDELINES ARE EXCEEDED.
3. Regular shoes or boots are to be worn with socks in the classroom and lab.
Sandals and shower shoes may not be worn in the classroom and lab.
Students who fail to meet satisfactory standards relating to the dress code will be sent home, and or counseled by the Department Head; and if no improvement is made, enrollment may be terminated.
SAFETY RULES AND REGULATIONS ACR 1336
1. Absolutely no horseplay in the lab or classroom
2. No running or jumping over things in lab or classroom.
3. Do not operate any equipment unless an instructor is present in lab.
4. Know the location of the fire extinguisher. It is located on the southwest wall of the lab, near the door to the hallway.
5. Keep tools and tool box out of the free walking area in the lab.
6. Do not stand on chairs or tool boxes when working on equipment.
7. Under no circumstances work around a wet floor. Clean up any water immediately if not sooner. Many of the high efficiency units in the lab produce a lot of condensation (water) and they are not hooked directly to drains.
8. Safety Glasses will be worn at all times in the lab. This also applies to OSUIT personnel.
