Applying, approval and booking the exam

In February 2026 Megan sat down at Linda's desk to apply. Dale had applied for his own master license in a different era, on paper, to a city office, and his advice was limited to one sentence: "Make it easy for them to say yes." Linda had a better plan. She had read the board's application instructions and the exam vendor's candidate bulletin, and she had a checklist that turned the process into six steps: apply to the board, answer any questions, receive the authorization, book the exam with PSI, take the exam, and pay for the license.

Step 1: apply to the board

Iowa's process starts with the board, not with the test vendor. A candidate cannot simply book a master exam with PSI. The board first decides whether the candidate is eligible under chapter 401 and then authorizes PSI to let the candidate test. Applications go to the board through DIAL's online licensing system or on the forms the board publishes, with the fee the board sets. The application asks for identifying information, the license the candidate already holds, the route being used and any supporting documents.

For Megan the application was straightforward. Her Iowa journeyman license was already in the board's records, so the board could confirm its issue date and status itself. Linda still attached a short cover note showing the date of the journeyman license and the planned test month, and she checked that Megan's legal name matched her driver's license exactly, because the same name must appear on the authorization, the PSI booking and the ID Megan would show at the test center.

Applicants on other routes have more to gather. A Class B master moving up attaches the Class B license details. An electrician relying on an earlier local license includes proof of that license and the dates. A reciprocity applicant needs verification from the other state's licensing body. If anything is missing, the board's staff will contact the applicant, and the clock does not really start until the file is complete.

Step 2: board review

The board's staff reviews the application against the rules. For a straightforward application this is a check of records and documents. For an unusual one it can mean questions, a request for more documents, or referral to the board itself. Applicants should answer staff requests quickly and completely, keep copies of what they send, and note the date. If the board denies an application, the denial explains the reason, and the rules provide for further review.

Linda's habit is to log every contact with the board: date, person, method and what was said. It has saved Boone Ridge more than once, including the year a contractor renewal was misfiled and Linda could show exactly when it had been sent.

Step 3: the authorization

When the board approves the application, the candidate receives an authorization to test, often called an eligibility or authorization letter, and the board sends the candidate's details to PSI. According to the bulletin, an authorization is valid for a limited time and a limited number of attempts: six months or two attempts, whichever comes first, in the version current in 2025. After that the candidate needs a new authorization. This is another reason to apply only when you are ready to study and test.

Step 4: book with PSI

With the authorization in hand, the candidate books the exam with PSI, online or by phone. The bulletin lists the test centers that serve Iowa candidates, including several in Iowa. The candidate chooses a center, a date and a time, and pays the exam fee, which was 87 dollars for the master exam in the 2025 bulletin. The fee pays for one attempt. A candidate who fails pays again for the next attempt.

The bulletin sets rules for changing an appointment. A candidate who needs to reschedule or cancel must do so in advance, at least two business days before the appointment in the version Linda read, or the fee is forfeited. A candidate who misses the appointment, arrives too late to be admitted or lacks proper ID loses the fee. Megan booked a Saturday morning slot at the test center in Des Moines, about an hour from Ames, and Linda put the rescheduling deadline in the calendar along with the exam date.

Identification and admission

PSI checks identity at the door. The bulletin lists the forms of identification it accepts, which include a current government-issued photo ID with a signature, and the name must match the name on the booking. Candidates are photographed and must store personal items, including phones, watches and bags, in a locker or in their car. Candidates who arrive late may be refused admission and lose their fee. Megan laid out her license, her code book and the confirmation email the night before.

The bulletin also explains how to request testing accommodations for a disability. Requests go through PSI's process with documentation and must be approved before the exam is booked, so a candidate who needs accommodations should start early.

Step 5: take the exam

Lesson 4 covers the exam format and the references in detail. For planning, three points from the bulletin matter. The exam is taken on a computer at the test center. The candidate's own copy of the allowed reference is brought in and inspected. And the score report is given at the end of the session. A candidate who fails receives a report that shows performance by content area, which is worth studying before the next attempt. Retesting on the same day is not allowed.

Step 6: the license fee and the license

Passing the exam does not by itself create a license. After a passing score, the candidate completes the license step with the board and pays the license fee. Under 481 IAC chapter 401 the fee for a Class A master license was 375 dollars for a three-year license in 2026, compared with 75 dollars for a three-year Class A journeyman license. The board then issues the license, and it appears in the public license lookup. Only then can a contractor list the new master as its licensed master.

Megan's plan therefore included one more step: once her license appeared in the lookup, Linda would update Boone Ridge's contractor license records to show Megan as a master employed by the company. Lesson 8 explains why that update matters.

# Megan's application calendar (dates invented for this course)
from datetime import date, timedelta
applied = date(2026, 2, 9)
approved = date(2026, 3, 16)              # authorization letter received
window_end = approved + timedelta(days=182)  # about six months
exam = date(2026, 5, 16)
reschedule_by = exam - timedelta(days=4)   # leave margin over two business days
one_year_as_journeyman = date(2026, 4, 14)
print("authorization valid to about", window_end)
print("exam after the one-year mark:", exam > one_year_as_journeyman)
print("days of authorization left on exam day:", (window_end - exam).days)
print("reschedule no later than", reschedule_by)

authorization valid to about 2026-09-14
exam after the one-year mark: True
days of authorization left on exam day: 121
reschedule no later than 2026-05-12

If the first attempt fails

Nobody at Boone Ridge planned on failing, but Linda wrote a plan for it anyway. A failing candidate leaves the test center with a score report that breaks performance down by content area. That report is the most valuable study document the candidate will ever get, because it shows exactly where the points were lost. The first step is to compare it with the practice miss log and decide whether the problem was knowledge, reading or time.

The second step is the calendar. Under the 2025 bulletin a second attempt can be booked under the same authorization as long as it falls within the six-month window, and a new exam fee is paid to PSI. Retesting on the same day is not allowed. If a second attempt also fails, chapter 401 requires a six-month wait and 12 hours of continuing education before a third, and a new authorization will be needed. A candidate who fails narrowly and has months left on the window is often best served by four to six weeks of targeted study rather than an immediate retest.

The third step is honesty with the employer. A contractor counting on a new master to qualify its license needs to know when the date slips, because the company's own plans may depend on it. Dale's license was still active, so a delay would cost Boone Ridge nothing but patience. A contractor whose only master has left the company has far less room, and lesson 8 explains what the rules require in that situation.

Choosing a test center and a time

PSI's Iowa centers and nearby out-of-state centers have different schedules, and popular Saturday slots fill early in spring. A candidate who works during the week may still find a weekday morning worth a day off, because a four-hour exam taken after a full shift is a different exam. Megan chose a morning slot because her practice scores were consistently better before noon, and she drove the route to the Des Moines center a week ahead so that the morning would hold no surprises.

What the costs look like

Linda added up the costs for Dale. The board's application fee, the PSI exam fee of 87 dollars, the master license fee of 375 dollars for three years, a new copy of the 2023 NEC with permanent tabs, and a practice exam package. Boone Ridge paid all of it, along with Megan's time on the exam day, because the company's contractor license would depend on her. Many Iowa contractors do the same, and some ask the new master to stay with the company for a period in exchange. Boone Ridge's agreement with Megan was a handshake, and she preferred it that way.

Linda's last piece of advice was to keep every document from the process in one folder: the application, the board's correspondence, the authorization, the PSI confirmation, the score report and the license. A master will be asked about these dates again, by insurers, by customers on public projects and sometimes by the board itself, and a single folder answers all of them in a minute.
