Accredited Drug Testing provides a comprehensive online/web-based Urine Drug Testing Collector Training and Certification course in Montebello, CA for persons required as part of their responsibilities to perform or supervise urine drug testing specimen collections. The collector training program may be completed with or without the required mock collection proficiency assessments. Upon completion of the training program, students will receive a certificate of successful completion of the training course. In Montebello, CA to be qualified/certified as a DOT urine drug test collector, you must satisfactorily complete both the training course and a minimum of 5 error free proficiency mock demonstrations.
The Drug Test Collector plays a critical role in the workplace drug screening process. Along with the employer, the testing facility and the Medical Review Officer (MRO), the collector is an essential part of a system developed to ensure drug-free workplaces for the sake of public safety.
As the collector, you are the only individual in the drug-testing process who has direct, face-to-face contact with the employee. You ensure the integrity of the urine specimen and collection process and begin the chain of custody that includes the laboratory; the MRO; the employer; and, possibly, the courts.
This training is a professional-level course that provides the knowledge and skills to qualify Drug Test Collectors to perform U.S. Department of Transportation-regulated drug tests and non-regulated tests. Course participants also have the option of becoming professionally certified after completion of this course. This designation confirms that the collector is committed to the highest standards in the drug and alcohol testing industry.
The Course
This professional-level course meets the regulatory standards of U.S. Department of Transportation (DOT) rule 49 CFR Part 40 and provides a solid foundation for a wide range of testing programs.

How to become a DOT Qualified Urine Colletor?
To become qualified as a collector, you must be knowledgeable about Part 40 regulations, the current "DOT Urine Specimen Collection Procedures Guidelines," and DOT agency regulations applicable to the employers for whom you will perform collections, and you must keep current on any changes to these materials. You must also (1) successfully complete a qualification training program and (2) pass a monitored proficiency demonstration, as required by DOT regulations [See 49 CFR Part 40.33 (b-c), effective August 1, 2001]. Please note: there is no "grandfather" clause or waiver from this requirement. A collector's qualifications are not location/collection site specific, and their eligibility will follow them anywhere DOT Agency regulated urine specimens are collected. There is no requirement for qualified collectors to register or to be on any federally-maintained or federally-sponsored list, but they are required to maintain (for Federal inspection) documentation of successful completion of their training and proficiency demonstration requirements.
How to Take the Course
The Drug Test Collector Training involves multiple parts that need to be completed in a specific order to achieve certification.
- Before starting the training, the collector must:
- review 49 CFR Part 40 and be familiar with the regulatory language;
- review the DOT Urine Specimen Collection Guidelines;
- review "Instructions for Completing the Federal Drug Testing Custody and Control Form for Urine Specimen Collection"
- watch DOT's 10 Steps to Collection Site Security and Integrity video.
- and download the sample Custody and Control Form. This form guides the entire drug-collection process. Review the document and have it at hand through the entire course. (All required materials are also available in the Reference Library.) NOTE: The 2017 version of the CCF is no longer current. If you intend to use it, you must attach a Memorandum for Record (MFR).
- Take the course Pre-Test to show familiarity with the subject matter based on a review of the materials provided.
- Complete the lessons of the training along with the required short quizzes.
- Take the final exam. A score of at least 90 percent is required.
- When you pass the online portion of this training, continue to the Next Steps lesson for instructions on how to set up five mock collections with a live examiner. These must be scheduled within 30 days of course completion and are required for qualification and certification.
- Once the mock collections are completed without error, you will be qualified and can perform both federally regulated and non-regulated drug test collections.
- To be certified, qualified collectors are asked to sign an agreement promising to adhere to the standards set in the training. The course administrator will then issue a certification form documenting that the collector is both a USDOT Qualified and Professionally Certified Drug Testing Collector. Contact the course administrator for more information.

Local Area Info: Montebello, California
Montebello (Spanish for beautiful mountain) is a city in Los Angeles County, California, United States, located in the southwestern area of the San Gabriel Valley on 8.4 sq mi (22 km2) 8 mi (13 km) east of downtown Los Angeles. It is considered part of the Gateway Cities, and is a member of the Gateway Cities Council of Governments. In the early 20th century, Montebello was a well-known source for oil reserves. At the 2010 census, the population was 62,500. The estimated population as of July 1, 2013 was 63,495.
Before the arrival of the Spaniards in the area known today as Montebello, the land along the Rio Hondo River was populated by the Tongva (Gabrielino) portion of the Uto-Aztecan family of Native Americans. The Tongva occupied much of the Los Angeles basin and the southern Channel Islands - Santa Catalina, San Nicolas, San Clemente and Santa Barbara; when Spanish explorer Juan Rodrigues Cabrillo arrived off the shores of Santa Catalina in 1542, he was met by the Tongva people. Because the language of the Tongva was different from the neighboring tribes it was called "Gabrielino" by the Spanish. As more non-natives arrived and settlements were established, illness and disease came with them. By 1870, the area had few remaining indigenous inhabitants as disease brought by the Europeans killed many of the Tongva.
Father Angel Somera and Father Pedro Cambon, both Franciscan missionaries, founded the original Mission San Gabriel Arcangel on September 8, 1771; the location is today near the intersection of San Gabriel Boulevard and the Rio Hondo River. The establishment of the mission marked the beginning of the Los Angeles region's settlement by Spaniards and the fourth of twenty-one missions ultimately established along California's El Camino Real. The mission did well initially as a farm and cattle ranch. Six years after its founding, however, a destructive flood led the mission fathers to relocate the establishment farther north, to its current location in what is the present day city of San Gabriel. The original mission site is now memorialized as California Historical Landmark #158.
