Draft Criteria for the Qualification of Certification Programs for Irrigation System
Auditors under EPA's Water Efficiency Program
1.0 Scope and Objective
This specification establishes criteria for the qualification of certification programs for irrigation
auditors under EPA's Water Efficiency Program. It applies to irrigation professionals who
assess the proper functioning of existing irrigation systems, perform water audits, and
recommend watering schedules. The purpose of the qualification is to identify programs that
certify irrigation auditors with demonstrated ability to apply water efficiency concepts in their
practice. An irrigation auditor who holds an EPA Water Efficiency Program qualified
certification should be capable of auditing irrigation systems with water efficiency being a
fundamental component of their practice.
2.0 Qualification Criteria
To be qualified under EPA's Water Efficiency Program, the certification program must meet the
following criteria:
2.1 Independent Oversight Committee
The certification process provided by an organization must be supervised by an
independent oversight committee. The oversight committee must be established by the
organization and be composed of at least three professionals who are recognized for their
expertise in the irrigation field. Full time employees of the organization must hold less
than half of the oversight committee positions. The committee must be able to exercise
independent judgment and oversight to assure the integrity of the certification process.
2.2 Experiential Requirement
The certification must require that the applicant have proof of successfully completing at
least one irrigation audit either before sitting for the exam or within a specified time period
following the exam as established by the oversight committee. The oversight committee
must have established the standard of proof for the experiential requirement.
2.3 Exam Requirement
The certification must include a requirement for the successful completion of an exam or
series of exams. Testing procedures must be established or approved by the oversight
committee.
2.3.1 Exam Content
The exam process should be structured so that passing practitioners must have
demonstrated proficient applied knowledge in the following subject areas:

• Distribution uniformity
• Precipitation rates and irrigation scheduling
• Water pressure and impact on sprinkler performance
• Auditing Process
• Soil/water/plant relationships
• Water budgeting and consumption
• System maintenance
Specific exam questions should be established or approved by the oversight
committee.
2.3.2 Exam Passing Score
The oversight committee should establish the passing score. The passing score on
an exam must provide an objective level of assurance that the concepts listed
above are understood and can be applied by the practitioner.
2.3.3 Quality Assurance/Quality Control
The examination process must include the following QA/QC elements:
• The technical content of exam questions should be established or
approved by, and periodically reviewed by the oversight committee to
ensure that the exam meets the requirements specified in Section 2.3.1.
In addition, an independent academic institute or professional testing
organization must review the exam questions to ensure that they
accurately test the subject material. The exam question review process
should be conducted at least once every two years, or more frequently
as determined by the oversight committee.
• Exams must be administered by an independent academic institute, a
professional testing organization, or an irrigation professional certified
in the subject matter.
• Exams must be graded by an independent academic institute,
professional testing organization, or a certified irrigation professional
not involved in the training or proctoring of the practitioner being
examined.
• The security and integrity of the test questions and test processes must
be protected at all times.
2.4 Renewal Process
The certification must have a renewal process with a set periodicity.

2.4.1 Expiration
A certification must be renewed at least once every two years, or more frequently
as established by the oversight committee.
2.4.2 Maintained Proficiency
One aspect of the renewal process must require the submission of documentation
that the practitioner has maintained proficiency in the subject matter (e.g.
continuing education units). The oversight committee should establish valid
documentation requirements of maintained proficiency.
3.0 Application for Qualification
The organization seeking to qualify must submit an application to EPA's Water Efficiency
Program for review. Qualification will be granted upon the approval of an organization's
application by EPA's Water Efficiency Program staff. The application should document that the
organization's certification process meets the criteria listed in Section 2.0. The application must
include the following materials:
3.1 Letter of Intent
The letter of intent serves to introduce the organization's certification program and should
include a background section that describes their certification and reason for seeking
qualification under EPA's Water Efficiency Program. The letter should include a statement
attesting to the validity of information submitted, and be signed by the chairman of the
oversight committee responsible for the certification program and an officer of the
organization.
3.2 Identifying Information
Provide the following identifying information for this application: a) Title of certification,
b) Name and address of certifying organization, and c) Name, address, phone number, and
email address of point of contact with certifying organization.
