Day 30: How to Register for the Terraform Associate (004) Exam — and What to Expect on Test Day

Overview

The Exam at a Glance

• Name: HashiCorp Certified: Terraform Associate (004)
• Questions: 57
• Time: 60 minutes
• Format: Online proctored, taken from your own machine — HashiCorp's official description is "an hour-long multiple-choice exam"
• Cost: $70.50 USD (plus local taxes where applicable)
• Pass mark: HashiCorp does not publish the cut score. The widely cited figure is ~70%, but the result on screen at the end is simply Pass or Fail — no percentage.
• Validity: 2 years from the date you pass
• Prerequisites: None
• Retake policy: If you fail, you can retake after 14 days. The second attempt costs another $70.50.

The exam is delivered through PSI on behalf of HashiCorp. Everything — registration, scheduling, the test itself, results — happens through the HashiCorp Certifications portal.

Question Formats on TA-004

HashiCorp's official page describes TA-004 as "an hour-long multiple-choice exam" — and that's exactly what it is. The earlier versions of the Terraform Associate exam (and some third-party practice courses, including Bryan Krausen's bonus set) include fill-in-the-blank questions, but the current TA-004 form does not. Every question you see on test day will be one of these three formats:

• Multiple choice (single answer). The most common. One correct answer out of four. Read the stem twice — many distractors are technically true statements but don't answer the actual question.
• Multiple choice (multiple answer / "select all that apply"). Two or three correct answers out of four or five options, and the question tells you exactly how many to pick. Partial credit is not given — you have to get all of them right. These are the highest-risk questions on the exam.
• True/False. Usually a short statement about a specific behavior — "By default, terraform apply requires interactive approval." Read for absolute words (always, never, only) — they're often the trap.

The 20 fill-in-the-blank questions in Bryan's course are still worth doing — not because the format will appear, but because typing out commands, block names, and meta-arguments from memory is a sharper recall test than picking from four options. Treat them as a recall drill, not a format rehearsal.

How to Register

The registration flow is short but has a couple of places where people get stuck. Here it is end-to-end:

1. Start at the HashiCorp certification page. Go to hashicorp.com/en/certification — this is the marketing/overview page that lists every HashiCorp certification (Terraform, Vault, Consul, Boundary) at both Associate and Professional levels. Pick Terraform Associate and click Schedule an exam.
2. Sign in or create a HashiCorp account. The "Schedule an exam" button drops you onto developer.hashicorp.com/certifications/signin. Use a personal email you'll keep — the certificate and the digital badge are tied to this account, not to the company you happen to work at today.
3. Pay the $70.50. Card payment goes through Stripe. You'll get an email receipt immediately and an "exam credit" attached to your account. The credit doesn't expire on a fixed date but you should treat it like it does — momentum matters.
4. Land in the PSI scheduling portal. After payment HashiCorp redirects you to PSI Bridge (the proctoring vendor). This is a separate UI from the HashiCorp site and the styling change can be jarring — don't worry, it's the right place.
5. Run the system check. PSI will offer to test your webcam, mic, network speed, and browser before you schedule. Do this now, not the night before. Details below.
6. Pick a date and time slot. Slots are typically available 24/7 in 15-minute increments and you can usually book as soon as the same day, depending on proctor availability. Pick a time when you'll be alert and your house/office will be quiet.
7. Confirmation email. PSI sends a confirmation with the launch link. Bookmark it. The launch button only becomes active 30 minutes before your slot.

That's it. From paying to having a scheduled slot is usually under 10 minutes if the system check passes.

System Check Before You Schedule

The single most common cause of a wasted exam slot is a system check failure on test day. The PSI Bridge browser is finicky:

• Only Chrome, Edge, or the PSI Secure Browser are supported. Firefox and Safari are not.
• The proctoring software needs camera, microphone, and screen-share permissions at the OS level. On macOS this means System Settings → Privacy & Security → grant permissions to your browser before the test, not when prompted (the prompt sometimes gets blocked).
• A second monitor must be physically disconnected, not just turned off. Same for any virtual desktops.
• A wired connection beats Wi-Fi, but Wi-Fi works if you're getting a stable 5 Mbps up/down. Run the PSI speed test from where you'll actually take the exam, not from your coffee store.
• VPNs, corporate proxies, and aggressive firewalls will block the proctor connection. Take the exam from a personal network if you can.

Run the system check the moment registration completes. If something fails, you have time to fix it. If you wait until the morning of the exam, you don't.

What's Allowed in the Room

PSI's online proctoring rules for TA-004:

• One government-issued photo ID matching the name on your HashiCorp account. Passport or driver's license is safest.
• A single monitor, a webcam (built-in is fine), and a microphone.
• A clear desk. No notes, no second devices, no books, no headphones (unless explicitly approved as an accessibility accommodation), no smartwatches.
• Water in a clear container is generally allowed. Coffee in a mug is generally not — check with the proctor at check-in if unsure.
• No bathroom breaks. The exam is 60 minutes; you're expected to stay seated and on camera the entire time. Plan accordingly.
• Room scan. Before the exam starts the proctor will ask you to pan your webcam around the room. Tidy up beforehand — anything visible can become a question.

Check-in usually takes 10–15 minutes and happens before your 60-minute exam timer starts. Log in 30 minutes early.

The 24 Hours Before

A short, opinionated checklist for the day before:

• Re-run the PSI system check on the exact machine and network you'll use. Things change — a Chrome update, a new firewall rule, a roommate's new device on the network.
• Confirm your ID is where you think it is. Sounds dumb, ruins exams.
• Stop studying the night before. Last-minute cramming on Domain 7 will not save you, but a bad night's sleep will sink you. Re-read your one-line notes from the Day 28 review loop for 20 minutes, then close the laptop.
• Plan the room. Clear desk, closed door, "do not disturb" sign if you live with people, phone in another room (you can't have it on you, even silenced).
• Eat normally, hydrate normally. Don't introduce new variables on exam day.

What Happens After You Submit

This part surprises people the first time:

1. Provisional result on screen. The moment you click submit, the screen shows Pass or Fail. No score, no domain breakdown — just the outcome. (HashiCorp deliberately doesn't publish percentages.)
2. Official result email from HashiCorp Certifications within a few business days. This is what you forward to employers if asked.
3. Digital badge from Credly within a week. The badge is verifiable, has a public URL, and is what you actually want to put on LinkedIn — not a screenshot.
4. The certificate is valid for 2 years. Recertification at expiry means re-taking the current version of the exam (TA-004 today, possibly TA-005 by then).
5. If you failed, the 14-day cooling-off period is enforced by PSI — you can't book a retake before then. Use the time to actually fix the gaps, not to re-cram. The retake costs the full $70.50 again.

The exam is scheduled. From here it's the 24-hour checklist, a quiet room, a webcam pan, and 60 minutes.

That closes the 30-day run. Whatever the result on the certification, the thing I actually wanted out of this challenge — building real infrastructure with Terraform every day for a month and writing about it in public — is already done.

Onwards.
