EPA	WaterSense Professional Certification
AA/stCl"ScnSC	Program Labeling System
1.0 Introduction
WaterSense, a partnership program sponsored by the U.S. Environmental Protection Agency
(EPA), seeks to protect the future of our nation's water supply by offering people a simple way
to use less water with water-efficient products, new homes, and programs. To achieve the
mission of the WaterSense program, EPA establishes partnerships with interested stakeholders,
such as product manufacturers, retailers, builders, water utilities, and other organizations. EPA
provides and maintains the WaterSense brand and develops national specifications for water-
efficient products, homes, and programs.
The purpose of the WaterSense Professional Certification Program Labeling System (program
labeling system) is to:
•	Define the organizational requirements that professional certifying organizations (PCOs)
must meet to earn the WaterSense label for a certification program.
•	Define the program roles and responsibilities of the PCOs and WaterSense.
•	Outline the application process for PCOs seeking the WaterSense label for a
professional certification program.
•	Ensure consistency in the evaluation of professional certification programs.
•	Ensure a base level of organizational competency regardless of the type of professional
certification applying for a WaterSense label.
PCOs can apply for organizational approval in accordance with this program labeling system
and the relevant WaterSense specification for professional certification programs (WaterSense
program specification). EPA is responsible for determining whether the PCOs meet these
general organizational requirements and the requirements specific to each WaterSense
program specification.
After EPA has developed a program specification for a given profession, a PCO that is
interested in receiving the label for a professional certification program shall apply to EPA with
documentation of the organizational requirements outlined in this program labeling system. If
those requirements are met, EPA will approve the organization as competent to offer a
professional certification program that could qualify to earn the WaterSense label. The PCO will
also submit documentation to EPA on the specific program for which the PCO is seeking the
label, and EPA will assess the program's conformance to the relevant WaterSense program
specification. If conformance is determined, EPA will sign a partnership agreement with the
PCO and allow the PCO to use the WaterSense label in conjunction with the respective
certification program.
2.0 Effective Date
Version 1.0 of this program labeling system shall be effective on July 24, 2014.
PCOs currently participating in the program shall be in compliance with Version 1.0 of the
program labeling system within one year from the effective date of this labeling system or no
later than July 24, 2015. Any PCO with an existing WaterSense labeled program that is not in
compliance with this program labeling system and does not have a labeled program by the
Version 1.0

WaterSense
effective date will be disqualified and shall immediately cease to use the label in conjunction
with that certification program as outlined in the WaterSense Program Guidelines. Until the
effective date of this program labeling system, EPA will continue to approve PCOs to earn the
label and label all certification programs in accordance with the existing WaterSense program
specifications (i.e., Versions 1.0).
After the effective date, all PCOs wishing to offer WaterSense labeled programs (e.g., new
PCOs or those offering certification through a program labeled under one or more of the existing
WaterSense program specifications) shall be approved by WaterSense in accordance with this
program labeling system and the relevant WaterSense program specification.
3.0 Scope
This program labeling system specifies the organizational requirements a PCO shall meet in
order to have a professional certification program labeled under one of the WaterSense
program specifications. This program labeling system does not apply to certified individuals, but
only to the organizations that develop and run the certification programs.
The WaterSense program specifications detail the certification program attributes that shall be
in place for a program to earn the WaterSense label. All final specifications, as well as any
technical clarifications, are posted on the compendium of program and product specifications
located on the WaterSense website.
This program labeling system, WaterSense program specifications, technical clarifications, the
WaterSense Program Guidelines, and the WaterSense Program Mark Guidelines provide the
minimum requirements and roles and responsibilities for PCOs and their operation of
WaterSense labeled professional certification programs.

•	Independent Academic Institution: A public or private institution dedicated to higher
education that grants academic degrees and is independent from the PCO seeking
testing review services.
•	Independent Oversight Committee: A committee established by the PCO that
supervises the certification program while exercising independent, professional
judgment. This committee shall act as a governing body for the certification program and
be responsible for establishing policies and requirements. It shall be composed of at
least three professionals who are recognized for their expertise related to the
certification program(s) they are responsible for overseeing. No more than one-third of
the positions may be held by employees of the PCO.
•	Professional Certification Program: A program that tests and maintains the
competency of practitioners in a particular field of service (e.g., irrigation, plumbing,
water management). A certification program differs from a certificate program in that a
certification program must require maintenance of competency through continued
education. This program labeling system applies only to certification programs.
•	Program Labeling System: This document specifies the organizational requirements
EPA has determined a PCO shall meet to have a professional certification program
labeled under one of the WaterSense program specifications.
•	Professional Test Administrator: A professional trained to maintain a secure, fair, and
consistent testing environment.
•	Professional Testing Organization: An organization that supports or provides for the
development or administration of standardized tests, typically on a fee-for-service basis.
5.0	Eligibility Requirements for Professional Certifying Organizations
EPA offers two eligibility paths for PCOs to have their programs earn the WaterSense label. The
following subsections describe requirements for each eligibility path a PCO may choose. For
clarification purposes, PCOs may fall into one of the following categories and are referenced
throughout the document as follows:
•	EPA Approved PCOs: PCOs that apply directly to EPA for organizational approval and
to have a professional certification program labeled. For organizational approval, a PCO
can choose one of two paths: third-party accreditation or WaterSense accreditation (see
Section 5.2).
•	Adopting PCOs: PCOs that have adopted an existing WaterSense labeled program as
described in Section 5.3. The PCO that provides the labeled program for adoption is
called the Parent PCO.
The application requirements to document that a PCOs eligibility requirements have been met
are outlined in Section 6.0.
5.1	General Eligibility Requirements for All PCOs
All PCOs that seek to have a professional certification program labeled in accordance with this
program labeling system shall:

•	Meet the eligibility requirements for EPA Approved PCOs (see Section 5.2) or Adopting
PCOs (see Section 5.3).
•	Be responsible for the impartiality of their professional certification program activities and
not allow commercial, financial, or other interests to compromise their impartiality.
5.2 Eligibility Requirements for EPA Approved PCOs
PCOs may choose one of two paths to meet the eligibility requirements of this program labeling
system. PCOs shall either follow the third-party accreditation path or the WaterSense
accreditation path. The third-party accreditation path is a more streamlined approach and
involves organizational or program accreditation to a national standard as described in Section
5.2.1. The WaterSense accreditation path involves documenting eligibility requirements to EPA
as described in Section 5.2.2.
PCOs may choose to meet the requirements of this program labeling system by meeting the
general eligibility requirements in Section 5.1 and obtaining accreditation in accordance with
one of the following standards (generally, or for any specific related or unrelated certification
program1):
•	ISO/IEC 17024, Conformity Assessment—General Requirements for Bodies Operating
Certification of Persons.
•	ST10, National Commission for Certifying Agencies' Standards for the Accreditation of
Certification Programs.
Accredited PCOs shall submit a certificate of accreditation when they apply for approval as
outlined in Section 6.1.
As an alternative to third-party accreditation, PCOs may submit documentation of the eligibility
requirements described in this section directly to EPA. PCOs that choose this path shall also
meet the requirements in Section 5.1. PCOs shall submit documentation demonstrating they
meet these eligibility requirements as outlined in Section 6.1.
5.2.2.1 Institutional Stability
•	The PCO shall have sufficient personnel resources with the necessary education,
training, technical knowledge, and experience to perform certification activities relevant
to the type, range, and volume of work performed.
•	The PCO shall have a management structure with overall responsibility for the following
elements:
o Evaluation and certification decisions.
1 The purpose of third-party accreditation is to demonstrate that the PCO is organizationally competent and capable
of offering program certifications, and that its capability has been assessed by an independent third party. As such,
the accreditation is not required to be related to the program the PCO intends to have labeled. EPA will evaluate the
specific certification program requirements according to the relevant WaterSense program specification.

requirements (e.g., experiential requirements) outlined in the relevant WaterSense
program specification have been met, as applicable. The procedures shall require that
the eligibility requirements are publicly available.
•	The PCO shall have procedures in place to establish and maintain current
documentation on the eligibility requirements of each certified individual.
5.2.2.5	Development and Maintenance of Certification Exams
•	The PCO shall have procedures in place to ensure that the technical content of exam
questions and passing scores are established or approved by the oversight committee(s)
to ensure that the exam meets the requirements specified in the relevant certification

6.0	Application
The application process for seeking organizational approval and the WaterSense label for a
specific professional certification program varies by PCO type, as outlined in the following
subsections. Figure 1 provides a summary of this process.
6.1	Application Requirements for EPA Approved PCOs
EPA Approved PCOs seeking the WaterSense label for a professional certification program
shall apply for EPA approval in accordance with this program labeling system. The PCO shall
also apply to EPA to have its certification program(s) labeled. The application shall include the
following documentation components:
•	Application for PCO Approval: This application documents that the requirements listed
in Section 5.0 of this program labeling system have been met. This application serves as
the mechanism for PCOs to demonstrate the general eligibility requirements have been
met. Once initially approved by EPA, a PCO does not need to submit the Application for
Professional Certifying Organization Approval upon subsequent applications for labeling
additional certification programs unless the additional certification programs are
administered differently from the previously approved certification program. If such
differences exist, the PCO must document those differences when they submit their
Application to Label a Professional Certification Program.
•	Application to Label a Professional Certification Program: This application
documents that the relevant WaterSense program specification criteria have been met. It
serves as the mechanism for a PCO to request the WaterSense label for a specific
certification program under a WaterSense program specification. As part of the
application, two letters of reference are required. The letters shall address how the
certification program has benefited water efficiency efforts on a regional, state, or on a
national level. One letter shall come from a utility and the other from a state agency or
regional water district. Both letters shall be signed and dated by the individual
responsible for the reference.
•	Partnership Agreement: This agreement is signed by both the PCO and EPA. The
partnership agreement is signed by EPA upon labeling of the first certification program
and is not required for subsequently labeled programs.
The application documents can be submitted individually in the order listed above, or as one
package. The partnership agreement will not be signed by EPA until a certification program has
been approved to earn the label. If a PCO is applying to have subsequent certification programs
labeled, only the Application to Label a Professional Certification Program shall be submitted for
the subsequent programs.
6.2	Application Requirements for Adopting PCOs
Upon notification to EPA, an EPA Approved PCO may act as a Parent PCO and offer their
labeled program for adoption. The Parent PCO shall offer an application to Adopting PCOs that
documents the requirements listed in Section 5.3 of this program labeling system. An Adopting
PCO shall submit this application to the relevant Parent PCO. The Parent PCO will review the
application and notify the Adopting PCO when the requirements are met. WaterSense has
available a sample Application for Adopting PCOs. A Parent PCO may use the sample

application or develop its own application. EPA reserves the right to review any applications
used by Parent PCOs to allow adoption of their WaterSense labeled program.
After the Parent PCO notifies the Adopting PCO that requirements are met, the Adopting PCO
will then submit the Application for Professional Certifying Organization Approval to EPA for final
approval. Once the application is approved by EPA, EPA will contact the Adopting PCO, and a
partnership agreement will be signed by both EPA and the Adopting PCO.

certification program has been approved to bear the label.
7.0 Authorization to Use the Label
EPA will evaluate the program application forms and documentation to determine if the PCO
meets the relevant requirements. EPA will notify the PCO of its determination. If all
requirements are met, EPA will provide the PCO with the WaterSense label (e.g., graphic files in
various formats), as well as a letter of approval authorizing the PCO to use the label in
association with that specific labeled program.

11.0 Amendments, Modifications, and Revisions
EPA reserves the right to amend these rules of procedure, which may include amending or
revising this program labeling system, revising any of the WaterSense program specifications,
or issuing technical clarifications as provided in the compendium of WaterSense product and
program specifications available on the WaterSense website.
Revisions to any of the WaterSense program specifications or this program labeling system can
occur due to technological and/or market changes that affect the usefulness of current
specifications and program labeling requirements to PCOs, consumers, industry, or the
environment or to clarify vague requirements.
Major revisions will generally include changes to the exam requirements, eligibility
requirements, and maintenance of proficiency requirements. Major revisions will only be made
following an open public process, including discussion with industry and other interested
stakeholders. Major revisions will typically require re-approval of existing programs to the new
specifications or this program labeling system, as appropriate. The transition period will be
identified in the relevant program specification or program labeling system, but will normally be
one year.
Minor revisions to program specifications or this program labeling system will generally be more
editorial in nature and serve to clarify vague or unclear requirements. Minor revisions will
typically not require re-approval of currently labeled programs. EPA will notify stakeholders
when program specification or program labeling system revisions are considered major or
minor.
To facilitate version control, EPA will designate a title, version number, and date for all of the
relevant documents it produces, as indicated below:
•	WaterSense Specification for [Program Category] or Professional Certification Program
Labeling System
•	Version X.Y
•	Month, Day, Year
