How to document your PE experience

"Progressive" is the word doing the work

Boards do not ask for four years of employment. They ask for four years of progressive engineering experience, and the adjective is not decoration. A reviewer is looking for judgment and responsibility increasing across the period: someone who moved from executing calculations that others specified toward choosing the approach, checking other people's work, and owning the outcome.

That is why work which is genuinely difficult can still fail to qualify. Drafting and CAD production, routine testing to a fixed procedure, technical sales, and purely managerial work are commonly discounted or excluded outright. That is not because they are easy; it is because they do not demonstrate engineering judgment growing. Conversely, a modest role where you were trusted to make and defend engineering decisions can count for more than a prestigious one where you did not.

What a board actually wants written down

How much your state asks for

Four years after an ABET/EAC-accredited bachelor's is the NCEES Model Law baseline and most boards follow it. What varies more than the headline number is everything around it: what a non-accredited degree costs you, and how many of your references must themselves be licensed.

Each row was checked against its source, the board's own statute, rules or published pages (for the first row, the NCEES Model Law), on Sep 24, 2026. Boards change rules; confirm with yours before relying on any row.

Rows that are easy to misread

California shows two years, and that is not a two-year rule. California frames licensure around six years of qualifying experience, of which an accredited degree supplies credit, leaving roughly two years to accrue after graduating. Civil applicants there also take California's own Seismic and Surveying exams on top of the national one.

New York shows no reference count, and that does not mean no references. New York verifies experience through employment affidavits on board-supplied forms rather than through a fixed number of referees. It is a different mechanism, not a lighter one. Washington, Illinois and Virginia show no count either: each job is verified on the board's own form instead (in Washington, by the licensed PE who supervised it; in Illinois, by your supervisor, a licensed PE or someone legally practicing engineering; in Virginia, by a licensed PE in that organization's engineering practice).

Who may serve as a reference, board by board, and when to ask them, is in PE references: who can sign, and when.

"Accredited" in the table means an engineering degree accredited by ABET's Engineering Accreditation Commission (EAC). An engineering technology degree, accredited by ABET's ETAC, is counted differently: Ohio and Texas ask for 8 years of experience with one, and the NCEES Model Law for 6.

Graduate degrees, and the two conditions nobody reads

In most jurisdictions a master's earns about one year of experience credit; a doctorate earns up to two in some (the Model Law, Illinois, North Carolina), but California, Virginia and Massachusetts cap all graduate credit at one year. A PhD is a total, not two years stacked on top of the master's year.

Two conditions catch people out, and both cost time rather than money. A graduate degree used to satisfy the education requirement generally cannot also be counted for experience credit: you spend it once. And degree credit is not earned concurrently with work, so finishing a part-time master's over three employed years does not add a credit year on top of those three.

The part that goes wrong is timing, not eligibility

Almost nobody fails to qualify because their work was not engineering enough. They stall because the record cannot be verified anymore. Every element of a PE application ultimately rests on somebody else confirming what you did (a supervisor, a project manager, a licensed engineer who watched you work), and those people move on.

Write down the project, the dates, your actual engineering role and your supervisor's license number and contact details while you still sit near them. It takes ten minutes per project and it is the difference between an application you assemble in an evening and one you spend three months chasing through LinkedIn.

• Record it the month it happens, not the year you apply. Memory for dates decays faster than you expect, and boards ask for months.
• Capture the reference's license number and state at the time, not just their name. A PE reference is only useful if the board can verify the PE.
• Describe the engineering, not the job description. What did you analyze, size, specify, or decide?
• Keep the part-time hours. Pro-rating is normal; guessing at it years later is not.
• Note what changed each year. Progression is the thing being assessed, and it is invisible unless you write it down.
• Read your own board's rules once, early. The table above tells you what to ask; it does not answer for them.

Common questions

What counts as qualifying engineering experience for a PE license?

Boards look for progressive engineering experience, not just time served. The word doing the work is 'progressive': they want to see judgment and responsibility increasing over the period: someone who moved from executing calculations others specified toward selecting the approach, checking others' work, and owning outcomes. Drafting, pure CAD production, routine testing to a fixed procedure, and sales or purely managerial work are commonly discounted or excluded. Rules vary by board, and your board is the only authority on whether a given role qualifies.

How many years of experience do you need for a PE license?

Four years after an ABET/EAC-accredited bachelor's degree is the NCEES Model Law baseline, and most states follow it. California is the notable exception among large states: it frames licensure around six years of qualifying experience, of which an accredited degree supplies credit, leaving roughly two years post-degree. What a non-accredited degree costs varies from nothing to four more years: four in Ohio, Texas and North Carolina; three in Georgia; two in California, Virginia and New York; none in Florida and Illinois (and under the NCEES Model Law) once the degree is shown to meet their education standard. Massachusetts adds none for an engineering degree that passes its Equivalency Appraisal but four for a technology degree, Washington decides case by case (up to four), and Pennsylvania uses separate routes.

Does a master's degree count toward PE experience?

In most jurisdictions a master's earns about one year of experience credit; a doctorate earns up to two in some (the Model Law, Illinois, North Carolina), but California, Virginia and Massachusetts cap all graduate credit at one year. A PhD is a total, not two years added on top of the master's year. Two conditions catch people out: a graduate degree used to satisfy the education requirement generally cannot also be counted for experience credit, and degree credit is not earned concurrently with work, so a part-time master's taken while employed does not stack a credit year on top of a worked year.

Do my PE references have to be licensed engineers?

Usually most of them. The NCEES Model Rules ask for five references, three of whom should be professional engineers (or other people the board accepts) who know your engineering work, and they exclude relatives and current board members. North Carolina's application follows that pattern: five references, three of them PEs. Other boards ask for fewer (Texas and Florida three, California four) or set no count at all: New York verifies experience through employment affidavits, and Washington, Illinois and Virginia have each job verified on the board's own form instead. Check your own board rather than assuming the common pattern.

When should I start recording my PE experience?

The day you start engineering work, which is years before you can use it. Every part of a PE application depends on other people confirming what you did: supervisors, project managers, licensed engineers who watched you work. Those people change jobs, retire, and stop answering email. The engineer who writes down the project, the dates, the role and the supervisor's contact details as it happens has a straightforward application. The engineer who reconstructs six years of work from memory in the month they apply is the one chasing a former manager through LinkedIn for a signature.

Is the NCEES Record the same as my state application?

No, though they overlap heavily. The NCEES Record is a verified file of your transcripts, exam results, employment history and references that NCEES keeps and sends to boards for you. Every U.S. board accepts it for comity licensure, a few require it for comity, and some accept it for initial licensure, so it is most valuable when you expect to be licensed in more than one state. Your state application is the board's own form. Both draw on the same underlying facts, which is the practical argument for keeping those facts in one organized place rather than assembling them twice.
