Attendance policy: Learners are expected to attend every class. Failure to attend class
will result in the loss of lab time and classroom instruction which will not be repeated.
Excessive absence from class will affect your grade. Missed exams can only be made up
with an excused absence and must be made up the following day a learner returns to
class. Missed quizzes cannot be made up and a grade of (0) will be given for that quiz. It
will be the responsibility of the learner to get the instructional material they missed.
Records of attendance will be kept and placed in your file.
Inclement Weather Policy
During periods of inclement weather, all classes scheduled BEFORE 9:30 a.m., will be cancelled. Learners will be
asked to report at 9:30 for their 9:30 classes. The classes that are cancelled will be made up according to a manner that
the individual faculty member has determined and which has been approved in advance by the appropriate Division
Chair and Dean; this makeup policy should be clearly stated in the course syllabus.
Academic Honesty Policy
KCTCS faculty and learners are bound by principles of truth and honesty that are recognized as fundamental for a
community of teachers and scholars. The college expects students and faculty to honor, and faculty to enforce, these
academic principles. The college affirms that it will not tolerate academic dishonesty including, but not limited to,
violation of the academic rights of learners (section 2.0) and student offenses (section 3.0).
Complaint/Appeal Procedure
1. Division Chair: Carolyn Bush
2. Learning Services Dean: Neil Brashear
3. Vice President of Learning Services/Provost: Dr. Kathy Smoot
For information about academic rights and academic offenses and the learner’s right to appeal, learners should be
referred to the KCTCS Code of Student Conduct found on-line at http://www.kctcs.edu/student/code.htm/
Withdrawal Policy
Learners may withdraw up to midterm and receive a grade of “W” without the instructor’s permission. After midterm,
and up until the last day of class, any learner may officially request a W grade, which may be given at the discretion of
the instructor. Each instructor shall state on the first or second class meeting the factors to be used in determining the
assignment of a W grade during the discretionary period. An instructor shall not assign a student a W grade for a class
unless the learner has officially withdrawn from that class. You should clearly state your withdrawal policy from
midterm up until the last day of class. If learners do not officially withdraw before the last day of class, they must
receive a grade of “E”.
Accommodations Policy
Learners needing accommodations should contact the local disabilities service representative to complete an
Accommodations Plan which will ensure that the student receive full benefits and that the instructor is aware and can
make the proper adjustments in his/her courses for the learner. The HCTC Disabilities Services Representative is
Melissa Johnson. Phone 606-487-3405; e-mail: MelissaD.johnson@kctcs.edu
Evaluation Method: All daily assignments and quizzes will be averaged during the
semester and will count as one exam. All exams will carry equal weight. An average of
exams, daily assignments, notebook, and final exam will determine your grade for the
semester.
The level of performance and completion of lab assignments will be the major grading
tool for the lab grade. Safety, performance level and attitude will also be a part of the lab
grade. This will be explained in detail during class.
Grading Scale
90-100
A
80-89
B
70-79
C

D
Below 60

Make-up Policy: Exams must be made up the following day a learner returns to class.
Exams can only be made up with an excused absence. It will be the responsibility of the
learner to make all daily assignments. All lab assignments must be made up before the
end of the semester or a grade of (0) will be given for each lab missed and averaged into
the final grade.
Class policies: Learners are expected to take part in class. Learners are expected to be
prepared for class (notebook, textbook, lab book, pen/pencil, calculator, hand tools). A
notebook must be kept and be neat and organized including all handouts and drawing.
Cell phones are to be turned off and not used during class. No food or drinks are allowed
in class.
