Professional Development Hours (PDH) are the standard unit of measurement for continuing education that Professional Engineers (PEs) must complete to maintain an active license. This requirement ensures that licensed engineers remain current with evolving technology, practices, and standards within the field. The exact number of hours a PE must complete depends entirely on the specific jurisdiction where they hold a license, as requirements are established by individual state licensing boards, not a single national entity.
Understanding PDH and PE Licensure
The mandate for continuing education is rooted in the regulatory responsibility of professional engineering boards to safeguard public health, safety, and welfare. By requiring PEs to complete Professional Development Hours, state boards enforce a standard of professional competency that extends beyond the initial licensing examination. This regulatory framework acknowledges that the field of engineering is dynamic, with constant advancements in materials, technology, and design methods.
The PDH requirement ensures practitioners are continually expanding and updating their technical skills to meet modern industry demands. This focus on lifelong learning helps mitigate the risk of outdated practices, protecting the consumer and maintaining public trust in the profession. Compliance with these educational hours is a condition for a PE to continue practicing legally within their state.
State-by-State PDH Credit Requirements
The numerical PDH requirement for Professional Engineer license renewal varies significantly across different jurisdictions. A majority of state licensing boards mandate continuing education, though renewal cycles and required hours differ widely. Many states operate on a biennial (two-year) renewal cycle, commonly requiring 30 PDH credits for that period.
Other states opt for an annual renewal cycle, typically requiring 15 PDH credits per year, which is equivalent to the biennial standard. Requirements are not universal; some states require a lower biennial amount, such as 18 or 24 PDH credits, while others, like New York, require 36 PDH over a three-year cycle. A PE licensed in multiple states must adhere to the specific rules of each jurisdiction, including different renewal dates and carry-over limits. Therefore, a Professional Engineer must consult the administrative code of their specific state board for the definitive requirement.
Mandatory and Specialty Credit Requirements
Beyond the total number of PDH credits required, many state boards impose additional mandates on the subject matter of a specific portion of the hours. This often includes a requirement for credits to be earned in topics such as professional ethics, rules of professional conduct, or state-specific laws and regulations. For instance, a state requiring 30 total PDH may stipulate that a minimum of two hours must be dedicated to a course on ethics.
These mandatory specialty hours ensure PEs receive regular updates on the legal and ethical obligations central to their practice. In Illinois, for example, the required three core hours include one hour each for ethics/professional conduct, state engineering statutes and rules, and sexual harassment prevention training. PEs must strategically select educational activities to satisfy both the overall numerical requirement and the mandatory subset of hours.
Acceptable Professional Development Activities
Professional Engineers can accrue PDH credits through a wide range of activities, provided the content is relevant to the practice of engineering and serves to maintain, improve, or expand their professional competency. The educational activity must have a clear purpose and objective that contributes to the advancement of professional skills and scientific knowledge. State boards generally recognize several categories of educational engagement as acceptable methods for earning credit:
- Formal coursework taken at an accredited college or university is an accepted method for earning PDH credits. These courses must be relevant to the PE’s practice and can include both credit and non-credit programs. PDH credits awarded are typically calculated based on the contact hours of the course.
- Attending professional seminars, workshops, and short courses sponsored by professional societies, technical associations, or continuing education providers is a common way to earn hours. These activities often cover the latest developments in technology, design standards, and industry-specific best practices.
- Educational programs developed and presented within an engineer’s company or organization can qualify for PDH credit. These in-house activities must meet the same standards as external courses, focusing on technical or managerial content relevant to the practice of engineering.
- A Professional Engineer can earn credit by teaching a course or making a presentation on a relevant engineering topic for the first time. This activity is recognized because the preparation and delivery of the material demonstrate a significant investment in professional knowledge.
- Active participation in technical committees of professional engineering societies or standards organizations may qualify for PDH credit. This work involves contributing to the development of codes and standards, which directly impacts the practice of engineering.
- The publication of technical papers, articles, books, or sections of books relevant to engineering can earn a PE PDH credits. The hours are typically awarded based on the effort and complexity involved in the writing and publication process.
- Receiving a patent for a new invention or process directly related to the PE’s area of practice is often considered an acceptable professional development activity. The work involved in the innovation and patent application process is recognized as a contribution to the engineering field.
Audits, Record Keeping, and Reporting
PEs must earn the required PDH credits and maintain meticulous records. Licensees are typically required to maintain detailed documentation of all completed professional development activities for a period that often ranges from three to six years, depending on the state. This documentation should include attendance certificates, log sheets detailing the activity, course descriptions, and the number of PDH credits claimed.
State licensing boards routinely conduct random audits of renewed licenses to verify compliance with the PDH requirements. During an audit, the PE must be prepared to submit all supporting documentation upon request to substantiate the hours reported on their renewal application. Failing to produce adequate records to support the claimed hours will be treated as non-compliance, even if the hours were genuinely completed.
Consequences of Non-Compliance
Failing to meet the Professional Development Hour requirements by the license renewal deadline constitutes a regulatory violation. Initial consequences for non-compliance can include fines or a probationary period, during which the engineer must complete the deficit hours. In more severe cases, the state licensing board may take disciplinary action against the PE’s license. This action can escalate to the suspension of the license, preventing the engineer from legally practicing until the requirements are fully met. The most severe consequence is the permanent revocation of the Professional Engineer license.
