ACADEMIC CREDIT Academic Credit According to the Ohio Department of Higher Education, one (1) semester hour of college credit will be awarded for each lecture hour. Students will be expected to work on out-of-class assignments on a regular basis which, over the length of the course, would normally average two hours of out-of-class study for each hour of formal class activity. For laboratory hours, one (1) credit shall be awarded for a minimum of three laboratory hours in a standard week for which little or no out-of-class study is required since three hours will be in the lab (i.e. Laboratory 03 hours). Whereas, one (1) credit shall be awarded for a minimum of two laboratory hours in a standard week, if supplemented by out-of-class assignments which would normally average one hour of out-of class study preparing for or following up the laboratory experience (i.e. Laboratory 02 hours). Credit is also awarded for other hours such as directed practice, practicum, cooperative work experience, and field experience. The number of hours required to receive credit is listed under Other Hours on the syllabus. The number of credit hours for lecture, lab and other hours are listed at the beginning of the syllabus. Make sure you can prioritize your time accordingly. Proper planning, prioritization and dedication will enhance your success in this course. The standard expectation for an online course is that you will spend 3 hours per week for each credit hour. II. ACCESSIBILITY STATEMENT If you need any special course adaptations or accommodations because of a documented disability, please notify your instructor within a reasonable length of time, preferably the first week of the term with formal notice of that need (i.e. an official letter from the Student Accessibility Services (SAS) office). Accommodations will not be made retroactively.

III. ATTENDANCE TRACKINGRegular class attendance is expected. Tri-C is required by law to verify the enrollment of students who participate in federal Title IVstudent aid programs and/or who receive educational benefits through other funding sources. Eligibility for federal student financialaid is based in part on enrollment status.Students who do not attend classes for the entire term are required to withdraw from the course(s). Additionally, students whowithdraw from a course or stop attending class without officially withdrawing may be required to return all or a portion of theirfinancial aid based on the date of last attendance. Students who do not attend the full session are responsible for withdrawing fromthe course(s).Tri-C is responsible for identifying students who have not attended a course before financial aid funds can be applied to students’accounts.Therefore, attendance is recorded in the following ways:• For in-person and blended-learning courses, students are required to attend the course by the 15th day of the semester (orequivalent for terms shorter than five weeks) to be considered attending. Students who have not met all attendance requirements forin-person and blended courses, as described herein, within the first two weeks or equivalent, will be considered not attending.• For online courses, students are required to login at least two times per week and submit one assignment per week for the first twoweeks of the semester, or equivalent to the 15th day of the term. Students who have not met all attendance requirements for onlinecourses, as described herein, within the first two weeks or equivalent, will be considered not attending.At the conclusion of the first two weeks of a semester or equivalent, instructors report any registered students who have “NeverAttended” a course. Those students will be administratively withdrawn from that course. However, after the time period inthe previous paragraphs, if a student stops attending a class or wants or needs to withdraw, for any reason, it is the student’sresponsibility to take action to withdraw from the course. Students must complete and submit the appropriate Tri-C form by theestablished withdrawal deadline.Tri-C is required to ensure that students receive financial aid only for courses that they attend and complete. Students reported for notattending at least one of their registered courses will have all financial aid funds held until confirmation of attendance in registeredcourses has been verified. Students who fail to complete at least one course may be required to repay all or a portion of their federalfinancial aid funds and may be ineligible to receive future federal financial aid awards. Students who withdraw from classes prior tocompleting more than 60 percent of their enrolled class time may be subject to the required federal refund policy.If illness or emergency should necessitate a brief absence from class, students should confer with instructors upon their return.Students having problems with coursework due to a prolonged absence should confer with the instructor or a counselor.
IV. LEARNING OUTCOMES ASSESSMENTOccasionally, in addition to submitting assignments to their instructors for evaluation and a grade, students will also be asked tosubmit completed assignments, called ‘artifacts,’ for assessment of course and program outcomes and the College’s EssentialLearning Outcomes (ELOs). The artifacts will be submitted in Blackboard or a similar technology. The level of mastery of the outcomedemonstrated by the artifact DOES NOT affect the student’s grade or academic record in any way. However, some instructors requirethat students submit their artifact before receiving their final grade. Some artifacts will be randomly selected for assessment, whichwill help determine improvements and support needed to further student success. If you have any questions, please feel free to speakwith your instructor or contact the Learning Outcomes Assessment office.
V. CONCEALED CARRY STATEMENTCollege policy prohibits the possession of weapons on college property by students, faculty and staff, unless specifically approved inadvance as a job-related requirement (i.e., Tri-C campus police officers) or, in accordance with Ohio law, secured in a parked vehicle ina designated parking area only by an individual in possession of a valid conceal carry permit.As a Tri-C student, your behavior on campus must comply with the student code of conduct which is available on page 29 withinthe Tri-C student handbook, available at http://www.tri-c.edu/student-resources/documents/studenthandbook.pdf You must alsocomply with the College’s Zero Tolerance for Violence on College Property available at http://www.tri-c.edu/policies-and-procedures/documents/3354-1-20-10-zero-tolerance-for-violence-policy.pdf
VI. CORONAVIRUS/COVID-19 STATEMENTStudents are responsible for adhering to all College health and safety guidance, including that which relates to the COVID-19pandemic.Public health requirements and standards are changing rapidly, and the College is adapting its guidance accordingly. Please checkyour Tri-C email and visit tri-c.edu/coronavirus regularly for updates.All students must adhere to the following general guidelines, until further notice:• Remain at home. Do not attend any in-person class or gathering.• Notify your instructor(s) if you are ill, have tested positive for COVID-19, or have been exposed to an individual who has testedpositive for COVID-19.• Wear a mask or face covering at all times, including, but not limited to: upon entering and exiting any Tri-C facility, in class, and in allcommon areas.• Maintain a distance of at least six feet between yourself and others at all times.• Provide the College with relevant information about your current health status and participate in any required on-site checks (e.g.,temperature checks).• Use only designated areas of Tri-C facilities, including entrances and exits. Sign in and out of Tri-C facilities as directed.The general guidelines listed above do not encompass all coronavirus-related guidance. These guidelines are subject to change atthe discretion of the College and under the direction of public health authorities. Students who fail to adhere to this guidance may besubject to disciplinary action under the College’s Student Code of Conduct and the Student Judicial Code.
