biological and physical environment.
C. Develop an awareness of self as an individual member of a multicultural
global culture.
The following competencies will be evaluated by the use of written exams,
oral exams, and demonstration practices.
Attendance policy: Students 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 student 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 student to get the instructional material they missed.
Records of attendance will be kept and give to prospective employers at their request.
Inclement Weather Policy
During periods of inclement weather, all classes scheduled BEFORE 9:30 a.m., will be cancelled. Students 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 students 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 students (section 2.0) and student offenses (section 3.0).
Complaint/Appeal Procedure (**Required for all faculty teaching eLearning Classes, optional for all other
faculty.)
1. Division Chair: Neil Brashear.
2. Academic Dean. Lelia Smith
3. Vice President of Academic Affairs / Provost: Dr. Kathy Smoot
For information about academic rights and academic offenses and the student’s right to appeal, students should be
referred to the KCTCS Code of Student Conduct found on-line at http://www.kctcs.edu/student/code.htm/
Withdrawal Policy
Students 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 student 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 student has officially withdrawn from that class. You should clearly state your withdrawal policy from
midterm up until the last day of class. If students do not officially withdraw before the last day of class, they must
receive a grade of “E”.
Accommodations Policy
Students 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 student. Hazard Community & Technical College contacts are
as follows: Hazard Campus, Knott County Branch, Leslie County Center, and the Technical Campus – see Doug
Fraley and at the Lees College Campus – see Cluster Howard.
**Add the additional statement to the Accommodations Policy for all eLearning courses (Web-enhanced, local,
hybrid, or all online)
Every effort is being made to meet the ADA 508 and W3C guidelines but if you find any distance learning class to be
limiting in any way please contact the course instructor and the Disability Services Representative, Hazard Community
and Technical College, One Community College Drive, Hazard, KY 40351; phone (606)-487-3086; email:
doug.fraley@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.

Make-up Policy: Exams must be made up the following day a student returns to class.
Exams can only be made up with an excused absence. It will be the responsibility of the
student 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: Students are expected to take part in class. Students are expected to be
prepared for class (notebook, textbook, lab book, pen/pencil, calculator, handtools). 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.
