Faculty who suspect violation of academic honesty, cheating, plagiarism, collusion, or abuse of resource materials may assign an academic penalty. 

Incidents of academic dishonesty are a violation of the Student Code of Conduct. An academic appeal process is afforded to students who desire to dispute a grade or any decision that affects the student's ability to complete and earn a grade for the course, provided it is not related to a violation outlined in the LSCO Student Code of Conduct, including aca­demic dishonesty. 

Nursing students are held accountable for any form of academic dishon­esty and will be withdrawn from the Nursing Program in the face of sub­stantial evidence of said action. Students who are withdrawn under this Policy are not eligible for readmission to the Program. 

• Academic dishonesty is defined as:any form of fraudulence, cheating, lying or deceitfulness in connection with the responsibility of a nurs­ing student in the classroom, clinical, or simulation lab setting

• any act that attempts to deceive or misrepresent the student's behav­iors, abilities, and/ or knowledge in order to affect or improve the student's standing in the RN Transition Program.

• Academic dishonesty includes, but is not limited to the

following:Cheating -

• Using unauthorized resources during exams, including but not lim­ited to cheat sheets, cell phones, internet sites, talking with other stu­dents about or during an exam or looking at another students' exam.

• Purchasing a paper or test information from an online course or an­other person.

• Use of any electronic devices including but not limited to cell phones, smart watches, headphones, earbuds, cameras, internet access, text messaging, crib sheets, hidden notes, markings on body, or other re­sources during exams or exam review.

Federal regulations require students who receive financial aid to have begun “attending” and participate substantially in each course for which they are enrolled on or before the official census reporting date outlined on the LSCO Academic Calendar. Students documented as “not attending” a course upon the census date are assumed (for financial aid purposes) to have not begun attendance for that course This negatively affects their financial aid eligibility and disbursement and requires the student to repay any financial aid funds that have already been disbursed . Attendance in an ONLINE course is verified by substantial participation in the course on or before the census date published in the LSCO Academic Calendar. Substantial participation in this online course is defined as logging in and completing/participating in at least one requirement of the course. Note: Simply logging in to your online course does not constitute attendance.

Hybrid classes are a mix of face-to-face and online environments. Students will be expected to attend class during the scheduled meeting time. (Include the policy on absences and tardiness.) In addition to classroom attendance, your weekly active participation in the online component (Blackboard and/or homework software) will be considered and expected.

Hybrid-Flexible (HyFlex) courses utilize a blended course design that allows students to choose how they will ATTEND their class sessions. Students can choose to attend sessions in-person or live online without attending class on campus. A watch later option is available to students taking a HyFlex course, however, students may utilize watch later sessions no more than three classes during an 8-week term or five classes during a 16-week term.

Students are strongly: encouraged to take exams as scheduled. However, in the event that an exam cannot be taken on scheduled date, the student is required to notify the instructor BEFORE the exam and give his/her reason. A make-up exam may be scheduled at the discretion of the instructors. In the event that a make-up exam is allowed, it must be taken within one week after the original exam date. All make-up exams, whether taken early or late, will have a ten-point penalty deducted. There will be NO exceptions to this rule. The Final Examination must be taken according to published college exam sched­ule with NO provision for makeup or rescheduling. 

• Face-to-Face - No food, drink, tobacco, cell phones, etc.

• Online - Since face-to-face meetings in the classroom may be replaced by online meetings through discussion boards, emails, and/or Blackboard Collaborate, students are expected to follow the rules of netiquette in these forums.

• Hybrid - When face-to-face meetings in the classroom are replaced by online meetings through discussion boards, emails, and/or Blackboard Collaborate, students are expected to follow the rules of netiquette in these forums.

• Hyflex - Whether attending in person or online (synchronously or asynchronously)—students are expected to engage respectfully and responsibly. Arrive prepared, minimize distractions, and participate actively using appropriate tools (e.g., microphones, chat, discussion boards). When joining remotely, keep your camera on when possible, mute your microphone when not speaking, and use the chat feature constructively. In the classroom, be mindful of peers who are joining online by speaking clearly and allowing space for all voices. All communication should remain professional.

Never attending or ceasing to attend classes DOES NOT constitute a drop or withdrawal. You remain registered until you request a drop from the instructor. Failure to act in a timely manner will result in an "F" grade for the course. It is the student's responsibility to follow up with the LSCO advising office to ensure that all drops/withdrawals are processed as desired.

The grade of "I" may be given when any requirement of the course, including the final examination, is not completed. Students seeking an incomplete should have completed 75% of the course requirements and be passing the course at the time of the request. Arrangements to complete deficiencies in a course should be made in advance of the end of the semester with the instructor. The instructor will process the Incomplete form online, and a confirmation will be sent to the student’s LSCO email.

Incomplete work must be finished during the next long semester. If not, the Office of Admission and Records must change the "I" grade to the grade of "F." The course must then be repeated if credit is desired. An "I" grade also automatically becomes an "F" if the student registers for the course prior to removing the deficiencies and receiving a grade change. The instructor may record the grade of "F" for a student who is absent from the final examination and is not passing the course.

Grade determination and awarding of grades in a course are the responsibility of the instructor and should be calculated according to college policy, procedures, and written details provided in the course syllabus. NOTE: Final grades are available to students within 48 hours of the instructor posting the grade in Banner. Students may view final grades by logging into MyGator and then accessing Gator Self-Service.

An academic appeal process is afforded to students who desire to dispute a grade or any decision that affects the student’s ability to complete and earn a grade for the course provided it is not related to a violation outlined in the LSCO Student Code of Conduct. If an informal conference with the faculty member regarding an academic complaint fails to reach the outcome requested by the student, the student may initiate the formal process. Even after initiating the formal complaint process, students are encouraged to seek informal resolution of their concerns. A student whose concerns are resolved may withdraw a formal complaint at any time.

Refer to the current catalog or for details on the formal grade appeal process.
