Purpose of the course: This course provides students with basic scientific concepts,
procedural theory and clinical applications in the study of blood or hematology. In this
essential medical science, students also study the fundamentals of hemostasis or
thrombosis. Information derived from hematological studies guides physicians in
differential diagnosis.

Assessment of Student Learning:
In both the didactic and the laboratory portions of the course, the student must achieve
78% or greater. Failure to achieve this minimum score will result in dismissal from the
program. In the laboratory portion of the course, the final grade will be recorded as
“Pass” or “Fail” and registered with the didactic portion.
2/16/2016

The following grading scale applies to all programs within the Allied Health Division:
100 – 92% = A
83 – 91% = B
78 – 82% = C
66 – 77% = D
65% and below = F
In the lecture portion of the clinical course, the final grade is derived from student
performance on examination(s) and/or assignments.
Grading/Student Assessment of lecture (didactic) portion of the course:
Final grade will be composed of:
1. Quizzes, study questions, assigned activities, class participation, etc. = 10%
averaged
2. Unit exams = 60% averaged
3. Final exam = 30%
TOTAL 100%
Grading/Student Assessment of laboratory (student laboratory and
clinicals) portion of the course:
1. Skills Checklist: Passing is 78% of the total points available
2. Professional Behaviors Evaluation: Passing is 78% of the total points
used
Final Pass/Fail clinical grade is the average of the Skills Checklist and the
Professional Behaviors Evaluation
Statement to Connect Course with General Education Outcomes or Technical
Program Outcome Statement: In compliance with MACC’S General Education
outcomes, the student who successfully completes this course will be able to:
a.
Demonstrate effective written and oral communication skills.
b.
Demonstrate an understanding of scientific principles and computational skills
and how to use them to solve problems and make informed decisions.
Program Outcomes and Assessments:
The Allied Health Department continually strives to meet the needs of the Medical
Laboratory Technician student through program improvements. This is a cooperative
effort that includes input from the faculty, student, Medical Laboratory Technician
2/16/2016

Advisory Board, and other appropriate agencies or entities. Students are assessed on
mastery of the course concepts and essential skills throughout the courses of the Medical
Laboratory Technician Program.
Other program assessments include clinical
performance criteria, essential skills mastery, the clinical process evaluation, ASCP
examination scores, placement rates, and follow-up surveys.
Instructor Policies/Expectations:
Instructors of this program expect the following from students:
1. Come to class prepared to discuss or apply important concepts by having read the
assigned material or reviewed materials for instrument operation.
2. Participate in class by listening, taking notes, and making contributions to
discussions.
3. Consult with faculty for clarification of difficult material or additional resources
to consult.
4. Respect the learning environment by averting distractions and disturbances such
as ringing cell phones and extraneous conversation in class.
5. Treat instructors and fellow students with consideration, concern, and fairness.
Academic Dishonesty: MACC board policy is as follows: “Academic dishonesty by
students damages institutional credibility and unfairly jeopardizes honest students;
therefore, it will not be tolerated in any form.” Forms of academic dishonesty include but
are not limited to the following: violations of copyright law, plagiarism, fabrication,
cheating, collusion, and other academic misconduct. Incidents of dishonesty regarding
assignments, examinations, classroom/laboratory activities, and/or the submission of
misleading or false information to the College will be treated seriously. The procedure
for handling academic dishonesty is outlined in the Student Handbook (Policy Handbook
M.010). In cases of alleged academic dishonesty, the burden of proof is on the student,
not on the instructor.
Attendance:
Students are expected to prepare for and attend all classes and clinical practice. Regular
attendance improves probability for success in the program. Habitual tardiness and
frequent absences are disruptive to the classroom and cause an unsafe environment in the
student laboratory. Instructors carefully plan learning experiences, so it is important as a
matter of courtesy and fairness to the class that all individuals be present. Students
absent for reasons beyond their control, such as verified personal illness or family illness
and/or death, can make up class work. If a student misses so many classes due to
extenuating circumstances that the instructor feels the student cannot catch up, the MLT
Program Coordinator will send a written report to the Director of Allied Health.
Students who miss two consecutive weeks of class during a regular sixteen-week
semester or the equivalent ratio of class time during a shorter session will be dropped
from that class unless acceptable justification is supplied to the instructor and the Dean of
Student Services. Additionally, students who miss more than one-fourth of the class
meetings during any scheduled session may be dropped from that class by the instructor
if, in the opinion of the instructor, the student does not have a reasonable opportunity to
succeed in the class.

Tardiness, make-up, and late work: Tardiness to class and clinicals is disruptive and
inconsiderate of others. Being on time is mandatory.
Make-up and late work: See the MLT Student Handbook for guidelines. Remember that
communication, accountability and responsibility are very important professional
behaviors.
Refer to the MLT handbook for the following policies:
Drop policy
Drug/alcohol policy
Grade appeal procedure
Student code of conduct
Student due process and grievance procedure
Student rights and privacy act
Use of computing resources
ADA Statement
Students who have disabilities that qualify under the Americans with
Disabilities Act may register for assistance through the Office of Access
and ADA Services. Students are invited to contact the Access Office to
confidentially discuss disability information, academic accommodations,
appropriate documentation and procedures. For more information, please
