What Is A EHC?

What an EHC Actually Is

An EHC is an Electrified Hardware Consultant: a professional who has earned the Electrified Hardware Consultant certification from the Door and Hardware Institute. The credential signals that its holder can specify, coordinate, and troubleshoot door hardware that is powered, monitored, or controlled electronically, and can do so within the code environment that governs those openings.

The acronym is shared by other, unrelated credentials in other industries. This article is strictly about the door-hardware credential, so if you arrived looking for a different "EHC," the details below will not apply to it. For quick-reference pages on the name itself, see our short explainers on what EHC stands for and the meaning of EHC, and for a broader overview of the credential see EHC certification.

Who Issues the Credential

The Electrified Hardware Consultant credential is administered by the Door and Hardware Institute (DHI), the professional association for the door, frame, and architectural hardware industry. DHI publishes the examination competency statements, sets the policies for proctoring and retakes, runs the continuing education program, and offers the training courses that align with the credential.

That single-source structure is useful for candidates: the authoritative answers about eligibility, fees, and scheduling come from DHI itself rather than from third parties. Where DHI's own pages are inconsistent (more on that below), the correct move is to confirm with DHI directly at the time you schedule.

What an Electrified Hardware Consultant Does

The work centers on openings that are more than a lockset and a closer. Typical responsibilities include:

• Reading and producing electrified hardware drawings, including riser and wiring diagrams that show how power and signals reach each opening.
• Coordinating hardware with access control, so that readers, electrified locks, door position switches, request-to-exit devices, and power supplies work as one system.
• Applying code to electronic openings, particularly where egress, fire-rated assemblies, and accessibility requirements constrain what electronic hardware may do.
• Troubleshooting openings that do not behave as designed, tracing faults through hardware, wiring, power, and controller logic.
• Writing specifications and reviewing submittals so that what is bought and installed matches the security and life-safety intent.

This is a consultative role. The value is in preventing coordination failures between the hardware supplier, the electrical contractor, the access control integrator, and the code official.

The Four Competency Areas on the Exam

DHI publishes four competency statements for the examination, and no percentage weights are published for them. That means you should not assume any one area carries more points than another. Treat all four as examinable and prepare accordingly. For a deeper walk-through of each area, see our complete guide to the four EHC content areas.

How the Exam Is Built and Delivered

DHI describes the full EHC examination as an eight-hour, paper-and-pencil exam with three question styles: short-answer, long-answer, and multiple-choice. The long-answer and short-answer sections reward being able to explain and justify a solution, which is a different skill from recognizing the right answer on a multiple-choice item.

The delivery details DHI has not fully reconciled

Candidates should know that DHI's published materials do not line up perfectly on delivery:

• The EHC page describes paper delivery and directs retakes into an online testing platform called Prolydian.
• DHI's exam information page for a sister credential states that the EHC multiple-choice component is offered through Prolydian with MonitorEDU live remote proctoring.
• DHI's general certification policy still names a different testing vendor and restricts remote proctoring.
• The general policy's two-retake limit conflicts with the EHC page's reference to a third-retake application.

We also want to be direct about what has not been verified: there is no confirmed current question count, no confirmed timer for the multiple-choice component by itself, no published passing score, and no published pass-rate statistic. If you see a specific pass rate or cut score quoted elsewhere, treat it with skepticism. Our pages on the EHC passing score and EHC pass rate explain what is and is not known.

The proctor requirement

For the paper examination, you arrange your own proctor. DHI's certification policies require that the proctor hold the same certification, meaning an EHC-certified proctor, and prohibit proctoring a family member or someone employed by the same company, division, or branch. The stated exception is staff proctoring at DHI's National and Micro Schools. In practice, this means you should start looking for an eligible proctor early, because the pool of certified holders outside your own employer may be small.

Fees, Eligibility, and Registration Mechanics

Two points stand out. First, there is no formal prerequisite to apply, so experience and coursework are recommendations rather than gates. Second, the membership price gap on the exam fee is large, which makes DHI membership worth pricing out before you register. Our EHC requirements guide covers eligibility in more depth, and the EHC certification cost breakdown shows how exam, training, and renewal fees add up. For scheduling considerations, see EHC exam dates and deadlines.

DHI Preparation Courses Behind the Credential

DHI's course catalog lists EHC403, EHC413, EHC423, and EHC490 as the preparation entries for this credential, and DHI recommends the first three for candidates. The published preparation content covers:

• Electrified hardware drawings
• Access control integration
• Low-voltage circuitry
• Troubleshooting
• Shop-drawing exercises
• Specification writing

It is important to read these correctly. They are unweighted preparation topics, not an exhaustive exam blueprint and not an official count of exam domains. Course hours, tuition, software exercises, and class materials do not tell you anything about exam timing, exam fees, or what resources you may use on exam day. Likewise, historical code editions cited in course materials should not be read as identifying the code edition any current exam is built on.

The practical takeaway is that the courses build the skills (drawing, wiring logic, troubleshooting, spec writing), and the exam's four competency statements define what you will be measured against. Use both lenses. Our EHC training overview and the EHC study guide go further into building a plan around them.

Who Hires and Values the Credential

The credential is most relevant where electrified openings are specified, supplied, and installed. Typical employers and roles include:

• Architectural hardware distributors and suppliers, where consultants prepare hardware schedules and review submittals for electrified openings.
• Door hardware manufacturers, in technical sales and product support roles that require explaining electrified product behavior.
• Architecture and consulting firms, where specifiers write door hardware sections that must coordinate with access control.
• Security and access control integrators, who need hardware fluency to tie systems to physical openings.
• Facility owners and institutions, such as campuses and healthcare systems, with large inventories of electrified openings to maintain.

We do not cite salary figures here because none are verified in DHI's published materials. For an analysis of earnings and value, see our EHC salary guide, our ROI analysis of the certification, and our EHC jobs overview.

Keeping the Credential Active

Earning the credential is not the end of the commitment. DHI's Continuing Education Program requires 30 CEP points every three years, with at least 24 of those points being technical. Renewal for a single credential costs USD 175 for members or USD 210 for nonmembers.

Sequencing Your Preparation by Domain

Because DHI does not publish weights, a sensible plan gives each area deliberate attention and builds from foundation to integration. One reasonable order, assuming a multi-week runway:

Product knowledge goes first because every other domain depends on it. Code goes after access control so you can stress-test real designs against it. The final block should be written practice, since the paper exam's long-answer and short-answer sections demand clear explanation, not just recognition. To gauge the effort involved, read how hard the EHC exam is, and keep our one-page EHC cheat sheet handy for review. You can also test yourself with the practice questions on our main practice test site.
