The New Plant Maintenance Program
The Mechanical Technologist and Electrical/Instrumentation programs have been merged into the Plant Maintenance program. Certificates were first issued under the newly reorganized Plant Maintenance Program July 1998. Mechanical Technologist and Electrical/Instrumentation certificates issued before July 1998 will remain valid as long as renewal status remains current.

Important Information

The Application Process
To become certified all applicants must complete the Application For Technical Certification, pay the application fee, have appropriate experience and education, and pass the written test. Application instructions and fee schedules are listed on the application. After applications are received at the CWEA office applicant information is compiled in the certification database. Application receipts are then mailed to all applicants. The experience and education given on the application is then reviewed by CWEA staff. Next, the applications are reviewed by TCP Local Section Chairs. If the application is approved, then the applicant will receive an eligibility letter giving test site information. If the application is rejected, the applicant will be notified and may be asked to supply more information if warranted. After completing the written test applicants are sent results. Those who pass will then be mailed certificates and wallet cards.

Test Administration And Admission
Testing Dates and Sites: Tests are given twice each year on the fourth Saturday of January and July in California, Michigan, and Nevada (see Application for Technical Certification for test schedule and test site map). Applicants who are eligible for the test will be mailed an acceptance letter and map to their test site. Special accommodations can be made for those who cannot take the test on Saturdays because of religious reasons by contacting the CWEA office at 510-382-7800.

Test Site Admission: Certificate candidates are required to show at least one valid government issued photo identification (State driver’s license or ID, or passport). Only after positive identification has been made by the proctor may a candidate’s test booklet be distributed. Candidates are not required to show their eligibility letters to enter the test site.

Test Security: All tests are closed-book. No reference material, programmable calculators, computers, or cameras are allowed in the test site. Candidates should only bring a scientific calculator and a few #2, or softer, pencils. All writing and notes must be in the test booklet. Candidates are not allowed to take any notes from the test site. Candidates who violate test site rules may be asked to leave the site and may be disqualified from that test. All violations of test security will be investigated by CWEA and appropriate action will be taken.

Test Design And Format
Test Design: All certification tests are designed to test knowledge and abilities required to perform Essential Duties with minimal acceptable competence.

The Essential Duties and Test Content Areas for each certification were determined by a job analysis and meta-analysis of job specifications by two independent psychometric consulting firms. The studies gathered data from on-site visits of over 31 water and wastewater agencies, interviews with 110 water and wastewater professionals, and analysis of more than 300 job specifications. All research was conducted under the guidance of the Technical Certification Program Committee, vocational sub-committees, and CWEA staff. All test questions are designed to measure at least one area of knowledge or ability that is required to perform an essential duty.

Test Delivery Mechanism: All tests are given in a test booklet with a separate form for marking answers. Tests are written in the English language only.

Test Format: All Plant Maintenance tests are given completely in the multiple choice format (see Sample Test Questions in this booklet for an example). The multiple choice format is considered the most effective for use in standardized tests. This objective format allows a greater coverage in content for a given amount of testing time and improves competency measurement reliability. Multiple choice questions range in complexity from simple recall of knowledge to the synthesis and evaluation of the subject matter.

Test Scoring
Scoring Method: All tests are mechanically scored by CWEA. The overall test score will determine if you pass or fail the test. The minimum passing score depends on the difficulty level of the test and is determined by the Modified Angoff Method. More difficult tests will have a lower passing score and less difficult tests will have a higher passing score. The minimum passing score is 75% of items answered correctly. However, the score may be adjusted downward depending on the difficulty level of the test. The exact passing score is determined after the test is administered.

How Passing Scores Are Set: Each time a certification test is given the questions are changed resulting in a different test form. Since each form has different questions the difficulty level of the test may not be the same from form to form. The passing score is developed as an overall estimate of minimal acceptable competence in the Test Content Areas by subject matter and testing experts. Passing scores are determined by an overall passing score, not by performance on individual Test Subject Areas, and are independent of other candidate’s scores. Partial credit will not be awarded for any test item answered incorrectly.

Test Postponement
Certificate candidates may postpone their exam date to the following test date only if a written request is received by CWEA no less than two weeks before the exam date. There is a $10.00 fee for postponement. No more than two postponements are allowed

for each application. If you wish to postpone a third time you must re-apply for certification and pay the full application fee. Postponement after the deadline is allowed only with an officially documented work related emergency or illness.

Test Reviews & Item Appeals
Test Reviews: Any candidate who has failed the written test may review his or her test in-person at a time and place to be determined by CWEA. Those requesting to review their test will be given one hour to view their test in a secure environment. No notes or any other form of recording will be allowed during the test review period. Test subject matter will not be discussed and score adjustments will not be made during the test review.

Item Appeals: Candidates who wish to appeal a specific test item must do so during the test by completing an Item Appeal form available from the test proctor. Item appeals will be evaluated and appropriate adjustments made during the scoring process.

Test Result Notification
Exam results are routinely mailed to certificate candidates approximately 6 weeks after the examination date. No results are given over the phone. All results are confidential and are only released to the certificate candidate.

Issue of Certificate
Certificates will be issued to all candidates who pass the examination. Certificates are mailed about two to three weeks after result notifications have been mailed.

Renewal of Certification
All certificates must be renewed annually. The first renewal is due one year from the last day of the month in which the certification exam was held. Certificate renewals less than one year past due are subject to the renewal fee plus a penalty fee of 100% of the renewal fee. Certificates more than one year past due are not renewable. Re-testing is required to reinstate certificates more than one year past due. Renewal notices are mailed to certificate holders two months before the due date. It is the responsibility of the certificate holder to ensure that his or her certificate(s) remains valid. Continuing education will be required for renewal after 2001.

Accommodations For Those With Physical or Learning Disabilities
In compliance with the Americans with Disabilities Act, special accommodations will be provided for those individuals who provide CWEA with a physician’s certificate, or its equivalent, documenting a physical or psychological disability that may affect the individual’s ability to successfully complete the certification examination. Written requests for special accommodations must be made no later than 2 weeks before the examination date.

Program Structure

Background
The Plant Maintenance Certificate Program combines the Electrical/Instrumentation Technologist and Mechanical Technologist vocations at the entry and the administrative/manager levels. At these levels, certificate candidates are expected to have some technical knowledge of both vocations. The level of technical knowledge for each of these grade levels is outlined in the sections explaining qualifications for Plant Maintenance Grade I and Grade IV.

Plant Maintenance Grade levels II and III are composed of separate Electrical/Instrumentation and Mechanical Technologist certifications. The level of technical expertise at these levels are more specialized than at the Grade I and Grade IV levels.

The Plant Maintenance Program structure is based on the same research and job analyses that are the basis of the test design. After analyzing job specifications at many agencies, and working with the feedback from professionals in the field, it was determined that the Electrical/Instrumentation and Mechanical Technologist certifications should be merged into a single Plant Maintenance occupational group.

Hierarchical Levels
The figure below diagrams the program structure. At the entry level is Plant maintenance Grade 1. This entry-level certification is designed to measure competence as a general plant maintenance worker. Grade I Plant Maintenance Technologists are expected to be able to assist either mechanical maintenance or electrical/instrumentation specialists performing fundamental duties. Certificate candidates should be familiar with the basic mechanical and electrical/instrumentation principles and duties listed in the Grade I Plant Maintenance Technologist section of this handbook.

Grade II and III are specialist levels where candidates may choose to demonstrate their competency in either electrical/instrumentation technology, mechanical technology, or both. At these levels candidates are expected to have a wide range of knowledge within their specialty. Many candidates find that the scope of knowledge required for successful completion of the test is beyond that utilized on a daily basis at their own workplace. Certificate holders are expected to demonstrate a wide range of knowledge, skills, and abilities because they should be able to perform the essential duties of mechanical technologists or electric/instrumentation technologists at any water or wastewater agency.

Grade IV is designed for managerial level personnel involved with plant maintenance. Certified individuals at this level are expected to demonstrate competency as managers of plant maintenance operations. Qualified candidates should be able to demonstrate the managerial functions, as outlined in the Grade IV Plant Maintenance section of this handbook as well as the ability to understand and make managerial level decisions regarding electrical/instrumentation and mechanical technology issues. Thus, Grade IV candidates should have a technical background in electrical/instrumentation and/or mechanical technology.

Certificates Issued Before July 1998
If you hold any valid Mechanical Technologist or Electrical/Instrumentation certificate issued before July 1998, you may continue to do so as long as you continue to renew annually. CWEA recognizes the following equivalencies:

Primary study references are recommended as the best sources for studying for the certification test. Supplementary study references are recommended as sources that will help to further your understanding of the subject matter beyond the primary references.

For each reference a “P” indicates Primary reference and an “S” indicates a Supplementary reference. Check the Grade column that corresponds to the grade level you will be taking to determine if a reference is Primary or Supplementary. Blank boxes indicate that the reference is not appropriate for that grade level.

For information about obtaining these publications call the phone number listed in the reference. If no phone number is listed contact the publishing agency directly or contact your local library or bookstore.

This reference list is intended to assist certificate candidate’s in their preparation for the Plant Maintenance certification tests. Use of these references does not guarantee successful completion of the test. There may be other publications that may be helpful to candidates preparing for the test. CWEA encourages you to identify and utilize other resources in preparing for your test.

Preparing For Your Test

This section addresses a few possible methods for preparing for the certification test. Since you are most familiar with your own abilities you are responsible for determining the best method for preparing for your certification test. Following the suggestions in this section does not guarantee you will pass the certification test.

Determining Your Preparedness: An individual’s preparedness for the certification test depends on a number of things including amount of practical experience in the vocation and years of education. If you are unsure how prepared you are for the test review the Essential Duties and Test Content Areas for the test that you are considering. If you are not familiar with most of the Essential Duties and Test Content Areas you should consider reviewing some of the material in the references listed for that grade level. You may also want to consider applying for a lower grade level if appropriate.

Using The Selected References: After evaluating how well prepared you are for the written test you may want to review some of the Selected References. The references in this list may be used to review those Test Content Areas that you are not familiar with or those for which you have little background. Well prepared candidates may only have to brush-up on a few topics while those less prepared may have to study extensively.

Test Preparation Classes: CWEA Local Sections host at least two test preparation classes in various parts of California. All applicants will be mailed the date and location of the nearest preparation classes. Usually these classes are given about two months before the test date and last a full day with Grades I and II material covered in the morning and Grades III and IV covered in the afternoon.

Using the Essential Duties and Test Content Areas as a Guide to Your Study: The Essential Duties (EDs) are a basic outline of the test subject matter. You can use the EDs as your study guide by referring to the EDs in the primary Selected References. As you study you will find that the TCAs are related to the EDs. Each test question is written to address at least one TCA and its related ED.

Frequently Asked Questions (FAQs)

Question: Is it required that I begin at the Grade I level then work my way up from there to higher levels?
Answer: No, you may take any test that you qualify for with your education and experience. However, if you are just starting out you can see by the education and experience requirements that you can work your way up the grade levels faster if you become certified at Grade I then achieve each successive certification as soon as you get the required education and experience.

Question: If I take a Grade II, III, or IV test will I have to know the Test Content Areas for the lower level tests?
Answer: Yes, the subject matter for each test builds on the subject matter for those tests below its grade level. A thorough knowledge of the Test Content Areas for the grade level that your are taking is most important to your preparation, but you should expect questions from any of the lower grade levels.

Question: Is continuing education required to renew my certification?
Answer: Not right now, but continuing education will be required for renewal around 2001.

Question: How long is the test?
Answer: All tests have about 75-100 questions and 3 hours are given for completion.

Question: Can I take more than one certification test at once?
Answer: Yes, but you can only take up to two at a time. You will be given a total of three hours to complete both tests.

Question: How do I get a receipt showing I paid for the test?
Answer: A receipt is sent to all applicants who have paid their fees about one month after the application deadline. Hold on to this receipt until the certification process is over in case you have to submit it to your employer for reimbursement.

Question: If I am applying for the Grade IV test do I need to be a Supervisor?
Answer: No, you just need to have about one year of supervision experience. You do not have to hold the title of “Supervisor.”

Question: Does my qualifying experience need to be at a wastewater treatment plant?
Answer: Not necessarily. Similar experience maintaining a water treatment facility is also acceptable as long as it generally fits the Essential Duties. Experience from other industries is also acceptable if it generally fits the Essential Duties.
