BASIC TECHNICAL MATH (2301)
Basic Technical Math presents the topics of arithmetic with whole numbers, common fractions, decimal fractions, percentage, measurement numbers, metric and English unit conversions, scientific notation, exponential operations and basic algebra - including the use of formulas and equation solving. The course is self-paced utilizing a text/workbook. Students may pretest to determine their skill level, with those meeting the competency level receiving credit for the course.

ADVANCED TECHNICAL MATH (2302)
This course is a continuation of Basic Technical Math with the added topics of practical plane geometry, practical solid geometry, practical triangle trigonometry and equation/quadratic equation solutions. The course is self-paced utilizing a text/workbook. Students may pretest to determine their skill level, with those meeting the competency level receiving credit for the course.
Prerequisite: 2301

ARCHITECTURAL DRAFTING AND BLUEPRINT READING (8008)
This course is designed to aid the student in becoming more competent in his/her ability to read and interpret trade blueprints. This is accomplished by classroom discussions of the importance of effective communication, neatness, familiarity with construction techniques and related symbols; drafting equipment and materials; and standard procedures and techniques. Skills will also be developed by hands-on use of these learned components in reading a set of construction plans, including relevant architectural views, mechanical, heating, plumbing and electrical plans and associated descriptive text necessary to generate a set of working house plans.
Prerequisite: 2301

REFRIGERATION AND AIR CONDITIONING I (1001)
An introduction to the principles of refrigeration and air conditioning systems will be provided during this course. Upon completion of the course, the student will be able to explain the basic refrigeration system and cycle. The student will also be able to identify the tools and materials related to the field. Topics covered will include theory, matter and energy, refrigeration and refrigerants, general safety, tools and equipment.
Prerequisite: 2301

REFRIGERATION AND AIR CONDITIONING II (1002)
This course is a continuation of Refrigeration and Air Conditioning I and will include an introduction to the many components of the basic refrigeration and air conditioning system. Upon completion of the course, the student will possess a general working knowledge of refrigeration and air conditioning components (i.e. compressors, condensers, evaporators and metering devices). The student will also be exposed to and use tools and test equipment of the trade. Other topics include soldering pipe, charging of systems and compressors.
Prerequisites: 2301, 1001

REFRIGERATION AND AIR CONDITIONING III (1003)
This course will provide the student with an introduction to the electrical controlling devices used in the refrigeration and air conditioning field. The student will acquire a working knowledge of electrical temperature controls. Basic control diagrams will be thoroughly discussed. Topics covered will include an introduction to refrigeration and air conditioning, meters, control diagrams and electrical control circuits.
Prerequisites: 2301, 1001, 1002, 9001

ELECTRICITY I (A.C./D.C. THEORY) (9001)
This course is designed to provide the beginning student with a thorough working knowledge of basic electricity. The course will cover such topics as Ohm's Law, series circuits, parallel circuits, generation of direct current, generation of alternating current, and basic transformer theory. The student will also wire several basic electrical currents.
Prerequisite: 2301

ELECTRICITY III (COMMERCIAL) (9003)
This course includes topics relevant to the design and installation of commercial electrical systems. Topics included, but not limited to, are electrical drawings, branch circuits and feeders and their installations, plus the studies of three-phase electric services, three-phase transformer systems and short-circuit calculations. Also included will be overcurrent protection and coordination of overcurrent protective devices, emergency power systems, motor and appliance circuits and other subjects (AC motors and megger usage). The aforementioned topics will be studied utilizing the latest adopted version of the National Electric Code (NEC) where applicable.
Prerequisites: 2301, 9001

BASIC MOTOR CONTROLS (9004)
This course focuses on developing the students understanding of the theory, operation, installation and maintenance of electric motor controllers and control circuits. The most common applications of electric motor starters and controllers are discussed and demonstrated, with practical lab work to give the student hands-on experience of electric motor controls.
Prerequisites: 2301, 9001, 9003

INDUSTRIAL TROUBLESHOOTING (9006)
This course is designed to aid the Industrial Electrician in everyday problem solving. An in-depth study of print reading for troubleshooting and how's of finding problems in control circuits will be covered.
Prerequisites: 2301, 9001, 9003, 9004

EPA CERTIFICATION (1022)
This course will provide the student with information pertaining to Section 608 of the EPA's Clean Air Act. This section pertains to stationary equipment, only not automotive. Upon completion, the student will be able to take the EPA certification exam that is offered as part of this course.

OSHA 10 & INDUSTRIAL HEALTH AND SAFETY (2202)
This course will discuss and demonstrate the importance of understanding and applying industrial safety principles and practices in the work environment. This training includes defining and discussing safety concepts, terms and definitions, recognizing best practices in accident prevention, understanding who is responsible for safety in the workplace and why. Students will also learn how to recognize workplace safety hazards and how to deal with them. Other topics such as tool usage, hazard identification, personal protective equipment and OSHA safety will be covered.

INTRODUCTION TO COMPUTERS (3035)
This course is designed to introduce the student to the basics of a personal computer. Topics covered include computer hardware and background (1st session), Windows basics (2nd, 3rd and 4th sessions) and a look at the four main areas of software (word processing, spreadsheets, databases and presentations - 5th and 6th sessions).

HUMAN RELATION SKILLS (2102)
This course will explore principles of human relations related to personal and occupational goals. Human relation principles to be explored include team skills, creative thinking, communications, goal setting, conflict management and self-image.

COMMUNICATION SKILLS (2106)
In this course, students will focus on communication as a survival skill in the workplace. We will learn how effective communication makes us better employees, employers and co-workers. We will study and practice the skills and oral and written communication. The goal of this course is to make students more perceptive and skillful speakers, listeners, readers and writers.

SUPERVISORY SKILLS (2105)
This course is designed for the prospective supervisor to develop the skills necessary to apply the principles of effective supervision on the job. The course covers the four functions of the management cycle (planning, organizing, directing and controlling), including ways of boosting productivity, communicating more effectively, handling problems, making correct decisions and reducing cost.
