Model Aquatic Health Code (MAHC) Module Development Process and Organization

How Were the Modules Developed?

The module development process involves a Steering Committee that guides the work of various Technical Committees which work on specific areas of the MAHC. The linked Project Outline document describes the MAHC vision, organization, goals, and objectives. The MAHC Process Diagram illustrates the sequence of events being undertaken as part of the MAHC process.

How is the MAHC Organized?

This draft outline or "strawman" provides a framework for discussing the MAHC content and helps users identify where various modules fit within the overall code. The "strawman" delineates cross-cutting issues requiring collaboration and deliberation by multiple Technical Committees. As with any "strawman," the numbering format, organization, and structure are subject to change as the MAHC progresses.

MAHC Strawman Outline [PDF - 14 pages]

The MAHC modules are organized in a series of columns (see figure below). The left-most column has a short keyword summary describing the information contained in the corresponding code language. Items deemed most critical to protecting public health are indicated in red font with an asterisk. The middle two columns show the section number and draft code language, and the far right column has a letter grade based on the perceived reliability and accuracy of the material presented. The grading system is divided into three levels:

Grade A: Practice supported by science/research/data.
Grade B: Widely accepted practice not supported by science/research/data.
Grade C: No widely accepted practice. Proposed language not yet supported by science/research/data.

The current status of each module is summarized on the Modules for Review page.

How Are MAHC Modules Being Finalized?

Technical Committees are responsible for the technical content of MAHC Modules. As they create the module they send it periodically to the Steering Committee for input to ensure that the content and format integrates with the work being done by other committees and addresses the overall MAHC goals. This process involves many drafts of the modules before completion. Once the Technical Committee finishes the module and the Steering Committee approves the product, it is passed to the MAHC Editor. The module is then moved into final formatting. Additional annex information may be added by staff if further clarification is needed on the intent or direction of the MAHC and its associated language. Following completion of this process, the module is put through internal CDC clearance. Upon completion of CDC clearance, the module can then be posted on the MAHC section of CDC’s Healthy Swimming website for review.
