Over the years, IUOE local 501 has developed and implemented comprehensive training programs that are widely recognized as the best in a number of industries. Our aim is to train Apprentice Engineers, certify Journeymen Engineers, and maintain a world class workforce.

Additionally, the Local 501 Training Fund offers a broad range safety and health training for members. With support under Federal cooperative agreements and grants, our HAZMAT Program provides state-of-the-art OSHA and HAZWOPER (hazardous materials) courses and training materials to members.

IUOE Local 501 Joint Apprenticeship Training Center

The Joint Apprenticeship Training Committee (J.A.T.C.) is comprised of an equal number of representatives from the Union and the Contributing Employers, a consultant from the State of California Department of Apprenticeship Standards (DAS), an advisor from the Community College District, and a Training Director employed by the J.A.T.C. The J.A.T.C. is responsible for providing apprentices the best possible on-the-job training available, that you attend school regularly, and that you progress satisfactorily through the program. The courses are accredited with Los Angeles Trade Technical College as our Local Educational Agency (LEA), and certified through the State of California’s Department of Apprenticeship Standards.


Apprentice Code of Conduct

Always be on time for work. Keep your vehicle in good mechanical condition so you will be able to drive long distance, if required.

You should be properly dressed and neatly groomed. You have been told and realize that you must conform to your employer’s requirements in dress and hair codes.

You are expected to have the proper work clothes, shoes, etc.

You are expected to furnish a minimum amount of hand tools.

You do not have a choice of jobs or the location of jobs. You may be required to report to or transfer from any employers as directed by the Apprenticeship Coordinator.

You understand and realize that due to the type of work or industry in which you may be placed, that you may not receive some facets of our trade in “On-The-Job-Training,” such as boiler experience in the cold storage industry or air conditioning in the bakery industry. This will not affect completion of your Apprenticeship.

The Joint Apprenticeship Committee has no way of guaranteeing that you have classes and schooling pertaining to all phases of the Operating and Maintenance Engineer’s Training program.

You will be issued an “Apprentice Daily Record” book and given instructions on completing the sheets, which must be done daily. At the end of the month you must mail or bring the completed and signed “Apprentice Daily Record” to the offices of the J.A.T.C. The “Apprentice Daily Records” are due on or before 15th of the following month for hours worked on the previous month.

Anytime you are injured or disabled, please contact the Apprentice office.

If you are assigned an unfamiliar job, admit that the process is new to you and tell your supervisor you will do your best.



NEVER QUIT A JOB, or refuse a work assignment (EXCEPTIONS – SAFETY ISSUES). If you have a problem, do the job assigned to you as directed, and immediately contact your Training Director.

Remember you are from a select group, therefore dress, act, and speak in a respectable manner in the classroom, at Union meetings, and at work.

2021 Apprenticeship Program Exam

Dear Employers, Members, Applicants and Interested Individuals:

The Operating & Maintenance Engineers Apprenticeship & Training Trust Fund for Southern California would like to update you regarding Apprenticeship Testing. Apprenticeship Testing is typically conducted every two years, with 2019 being the last time we opened the application period for testing and processing. With that said, The Operating & Maintenance Engineers Apprenticeship & Training Trust Fund for Southern California will not be conducting the open application period for the Apprenticeship Program in 2021.

COVID-19 has brought hardships and uncertainty for the future, and because of that, we are unable to offer the Apprenticeship Program exam for 2021. It is impossible for us to offer the in-person exam with all the safety precautions and protocols that have been instituted by the State of California, Center for Disease Control (CDC), and Los Angeles County Department of Public Health.

Apprenticeship History

Since ancient times civilizations have lived, grown, flourished and died in direct relation to their ability to teach skills to younger generations. Traditionally, skills were passed on to succeeding generations by master craftsmen. Many of these skills required years of slow, laborious training to produce a craftsman worthy of his master.

Youths were sent to live with masters to learn a trade. Fathers and mothers taught sons and daughters from childhood. With limited economic opportunity and no formal education system, this early system of apprenticeship was vital to sustain the skills necessary to continue civilization and culture.

During the Industrial Revolution, apprenticeships were instrumental in teaching and training the skills necessary to run the machinery that resulted from the technological advances of the day. In many industries, it was and still is, the only way that job skills were taught and passed on to the next generation of workers.

Apprenticeship is nothing more than a formal, organized system of On-The-Job Training (OJT), in hand with Related Supplemental Instruction (RSI). The apprentice learns by doing and earns while learning. The primary objective of any apprenticeship program is to efficiently and effectively train workers to attain the competency to perform as journeyman.


The Operating and Maintenance Engineers Apprenticeship Program combines classroom instruction with on the job training in an intensive, long term program designed to train workers to meet the demands of very specific industries. It is good old fashioned American values combined with current technology to produce highly skilled, productive workers.

The program is a partnership between the Union and Industry, with very little need for government intervention. It draws on the resources of the Unions and the Industries, producing direct dividends to both through a more productive work force.

Training is industry, job, and machine specific. Training programs can be designed and customized to fit the demands of your specific industry.

The Operating and Maintenance Engineers actively recruits minorities and women, making it a good avenue to fulfill affirmative action employment. All applicants are effectively screened and thoroughly tested before any training is undertaken. They must have a High School diploma, General Education Development (GED) diploma, Test Assessing Secondary Completion (TASC), or High School Equivalency (HiSet), be at least eighteen (18) years old, and be proficient in Mathematics and English (reading and writing) at an eighth (8th) grade level or above. There is a six (6) month probationary period from date of the Apprenticeship Program start date, with constant reviews coordinated by the Operating and Maintenance Engineers program to ensure that the applicant is making progress both educationally and on the job.

Equipment and machinery in the classroom is kept current, so that what the apprentice learns in the Operating and Maintenance Engineers program can be specifically applied to the industry and job assignments.

The goal of the Operating and Maintenance Engineers program is to effectively use training and technology to improve the quality of workers’ skills and to transfer those skills back to the work force.

Targeted Industries include:

• Major Hotel Industry
• Hi-Rise Office Buildings
• Manufacturing Plants
• Industrial Laundries
• State, County, and Federal Facilities
• Waste Water Treatment Plants
• Oil and Other Refineries
• Steam Plants
• Hospitals
• Other industries that require skilled operators of heavy duty industrial equipment.



Employers of all trades need employees with increasingly better and stronger skills to handle advancing technology. The Operating and Maintenance Engineers program provides employers with productive employees while the training process is taking place. It also provides ongoing training to keep the workforce state-of-the-art.

The program is an excellent screening process and takes the risk out of hiring new employees. All candidates must meet minimum requirements to be eligible to participate:

• Must be at least eighteen (18) years of age
• Must have a high school diploma or GED
• Must be in good physical condition
• Must prove U.S. citizenship or up to date work permit
• Must be fluent in English

The Operating and Maintenance Engineers Program can help employers meet Federal requirements for affirmative action. It also will keep employees up to date on government regulations – EPA, OSHA, AQMD, etc. Apprentices are provided an extensive, current library of reference material in the form of books that they have access to during their training time.

Participating employers have the advantage of an in-house training program, reducing the overhead expense normally associated with outsourcing training programs.

A study at the University of Pittsburgh determined that:

“Training programs that are successful in teaching, thinking, and learning skills, are programs that are patterned after elements that apprenticeship programs have used for years. Classroom instruction and on the job monitoring, allowing the employer to contribute to the training progress of the worker. These types of programs are responsive to the employers’ and workers’ need for flexibility and portability of the training from classroom to worksite.”



The Operating and Maintenance Engineers Apprenticeship Program begins with the administration every two (2) years of the TABE – Test for Adult Basic Education examination. This examination is given on an open basis to candidates recruited through newspaper advertising, social agencies, schools, trade magazines, etc. Candidates are placed on a list according to their test score results.

If, at the end of the two (2) year period the eligible candidate hasn’t been selected as an apprentice, the testing process must be repeated to maintain eligibility as a candidate for apprenticeship.

When an employer contacts the Operating and Maintenance Engineers, the resumes of top candidates from the eligibility list are sent to the Employer(s) for review. The Employer(s) may interview as many eligible candidates as they like.

After an eligible candidate is chosen, an Apprentice Agreement is signed and the eligible candidate is enrolled as an apprentice into the program. The apprentice works for the employer, receives On-the-Job Training and attends classes in the evening, usually two nights per week. Work hours and education hours, as well as grades, attendance, and performance are tracked. Apprentices must maintain a grade of “C” or better in each course and cannot miss more than two (2) classes per semester. The Joint Apprenticeship Training Committee is responsible for all educational expenses.

Most employers who would be interested in the Operating and Maintenance Engineers Apprenticeship Program are already paying into the Operating and Maintenance Engineers Training and Maintenance Trust Fund. This covers the cost of the program, so there are no additional expenses to participating employers.

This is a four (4) year apprenticeship program *. The Classroom instruction is designed to teach competence in all technical aspects of an occupation as well as how to make sound decisions and technical judgments. A report to Congress by the Office of Technology Assessment concludes that “Good training pays off— for the individual worker whose skills are upgraded, for the company seeking a competitive edge, and for the Nation in overall productivity and competitiveness.”

* Our Apprenticeship Program is currently pending approval to be changed to a five (5) year program, leading to an AS Degree in Operating and Maintenance Engineering.
