SCANS SKILLS: The Department of Labor has identified skill sets that U.S. employers want most in entry level
employees. It is our commitment to prepare every student with the knowledge and skills needed to succeed in today’s
dynamic environment. Toward this end the following skills will be included in this course:
 Manage money: uses or prepares budgets, makes forecasts, keeps detailed records to track budget performance, and
makes
Appropriate adjustments. Manage space: acquires, stores, allocates and uses materials or space efficiently.



Work on teams: works cooperatively with others and contributes to group with ideas, suggestions, and effort.
Reading: Locates, understands, and interprets written information in prose and documents including manuals,
graphs, and schedules to perform tasks.
Sociability: demonstrates understanding, friendliness, adaptability, empathy and politeness in new and ongoing
settings.
Students will be presented with a problem in which they will be required to use specifications to develop a work plan. All
team members will be responsible for generating ideas, making suggestions as a part of developing the work plan. The plan
must include specific recommendations for acquisition, systematically storing, and allocating materials. Preparation of the
work plan will require locating and interpreting written information from documents and manuals as well as demonstrating
adaptability, understanding and politeness in accepting changes recommended by others in the class during their
presentation.

Evaluation of these skills will be based on the success of each team’s presentation of their work plan to the class.
GENERAL COURSE EVALUATION PROCEDURE: The student will be evaluated and receive a final grade based upon the
following criteria:



Laboratory work consisting of assigned technical drawing problems.
A full project.
Class and laboratory attendance, active participation in class, professional attitude and growth in terms of
technical skills development and teamwork within the laboratory environment shall be taken into consideration.
LAB REQUIREMENTS: Student can use computer at the labs or at home of his/her choice. The labs to be opened if there is a class in
session. If the lab is being used by other class, student is encouraged to ask the instructor before using the available computer. Lab
assistants, if any, are also available for technical help.
COURSE EVALUATION PROCEDURE: The student will be evaluated and receive a final grade based upon the following criteria:
 Laboratory work consisting of assigned technical drawing problems.
 A minimum of two tests: (a mid-term and a final examination):
NOTE: Individual instructors may schedule more tests if desired.
 Class and laboratory attendance, active participation in class, professional attitude and growth in terms of
technical skill development and teamwork within the laboratory environment shall be taken into consideration.
Note: Students are required to initial his/her name on the provided form (Green Form) upon showing up to the class.
GRADING PROCEDURE:
A = 90 –100
B = 80 – 89
C = 70 – 79
D = 60 – 69
F = below 59
The drawing portion of the above evaluation criteria shall be based on the layout, dimensional accuracy, neatness, and timely completion.
LATE ASSIGNMENT POLICY: Students are encouraged to turn assignments in on time if at all possible. This allows the instructor to
grade the work, return it to the student and the student use the feedback as a learning tool. Reduction of points could be applied to late
submissions. In general, a minus 5% would be applied to every late week.
MAKE-UP TEST/PROJECT POLICY: The student must request a make-up test and it should be scheduled at the earliest possible
date following the quiz (or mid-term) missed. NO make-up test are given for the final examination.
EXTRA CREDIT: Extra credit work is offered only to assist students that that have a grade range of “D” or “F” at the mid-term break.
This work cannot be substituted for regular assignments and can only raise the final grade to a maximum of a “C”.
PROGRAM ACCESSIBILITY (ADA): The Houston Community College, Drafting and Design Technology Program is committed to
making all aspects of the program accessible to individuals with disabilities. Students with disabilities, as defined by the American with
Disabilities Act (ADA), are required to obtain certification of their impairment through the College ADA Certification Office. For
information contact the front office of the campus.
CLASS ATTENDANCE: You are expected to attend all lecture classes and labs. You are also responsible for all materials covered
in either lecture or lab. In the case of your absence, you must contact the instructor to obtain make-up assignments or arrange make-up
testing, either of which can be distributed at the instructor’s discretion. Class attendance is checked daily.
The instructor has the authority to drop you from the class for excessive absences, that is, you may be dropped from a course after
accumulating absences in excess of 12.5 percent of the total hours of instruction (lecture and lab).
For example: - A 3 credit hour lecture/lab class meeting 6 hours per week – 2 absences (12 hrs.) is 12.5% of the class.
- A 3 credit hour lecture/lab class meeting 3 hours x2 times per week – 4 absences (12 hrs.) is 12.5% of the class.
Administrative drops are at the discretion of the instructor. It is your responsibility to drop a course, should you choose not to complete
it. Failure to withdraw officially will result in you receiving a grade of “F” in the course.
Note: Although it is your responsibility to officially withdraw from a course, it is always a good idea to discuss any attendance problems with your
instructor first. Class attendance is very important, but your instructor may be able to help you catch up. If you become ill or know you are going to miss
class for some reason, tell your instructor as soon as possible.
Departments and programs governed by accreditation or certification standards may have different attendance policies.
RELIGIOUS HOLIDAYS: If you observe a religious holiday and miss class, you must notify your instructor in writing two weeks in
advance to arrange to take a test or make up an assignment. A religious holiday is "a holy day observed by a religion whose place of
worship is exempt from property taxation under Section 11.20, Tax Code."
