TOEIC Link Travel Authorization and Per Diem Vocabulary: The Request-Approve-Reconcile Cluster for Part 4 and Part 7

In TOEIC Link, a business trip is never just a plane ticket — it is a request, an approval, an advance, a daily allowance, and a settlement on return, and ETS can test every stage. A recorded voicemail from a travel desk tells an employee the authorization has been approved but the hotel rate exceeds policy, so only the capped amount will be covered (Part 4). A travel request form runs beside a policy memo, and a question asks what was approved, what the per diem covers, or how much must be repaid (Part 7 double passage). Because a trip always runs the same loop — request, approve, book within policy, draw an advance, claim the per diem, reconcile — ETS can set what was spent against what the policy allows and leave exactly one answer standing. Miss a term like travel authorization, per diem, cash advance, within policy, or reconcile the advance and a linked pair can slip in one move.

This article organizes the cluster by the trip lifecycle — request, approve, book, advance, claim, reconcile — because that lifecycle is exactly how ETS threads the pieces together. Because the trip's costs eventually land on an expense report, pair this first with the expense report and reimbursement approval cluster — the authorization is the promise, the expense report is the proof. And because much of the spending happens on a company card rather than out of pocket, contrast this with the corporate credit card and expense reconciliation cluster whenever the question turns from a daily allowance to a card statement.

Why travel authorization and per diem vocabulary is overweighted

Reason 1 — a claimed amount plus a policy limit is a ready-made linked set. The claim states what the traveler spent; the policy states what the company will cover. When a question asks how much will be reimbursed, the two numbers force one conclusion, exactly what a linked set needs. ETS asks the reader to match the claim to the cap, and only one reading survives.

Reason 2 — a trip runs on a fixed lifecycle. Because every trip follows the same order — request, approve, book, advance, claim, reconcile — ETS can ask "What still needs approval?" or "What must the traveler pay back?" with exactly one correct answer. The reader matches the order against the form.

Reason 3 — the terms are fixed travel-policy conventions. Travel authorization, per diem, cash advance, within policy, non-reimbursable, and reconcile the advance mean the same thing across every company travel program. That rigidity makes the cluster perfectly testable — and perfectly learnable. The collocation, not the isolated word, is the unit of memory.

The cluster, organized by the trip lifecycle

Stage 1 — requesting authorization

Verbs and collocations: request authorization, submit a travel request, seek approval, estimate the cost, justify the trip.

Nouns: travel authorization, travel request form, business purpose, estimated cost, cost center.

Before any booking, the employee submits a travel request, stating the business purpose and the estimated cost against a cost center. A Part 4 message confirms the request has been received; a Part 7 question about what the trip is for hinges on the stated business purpose, not on a later itinerary detail. Note that a request is not yet an approval — ETS uses the gap to test whether the reader knows the trip is only proposed.

Stage 2 — approval within policy

Verbs and collocations: approve the request, authorize travel, cap the rate, exceed policy, require justification.

Nouns: travel authorization, spending cap, policy limit, preferred vendor, approval threshold.

The manager approves the request, but only within policy: the hotel rate is capped, and anything that exceeds the policy limit needs extra justification. A Part 4 voicemail says the trip is approved but the chosen hotel is over the cap. A Part 7 question about why part of a cost was denied points to the policy limit — a distractor blames a missing receipt the memo never mentions.

Stage 3 — booking and the cash advance

Verbs and collocations: book through, use a preferred vendor, draw an advance, issue an advance, book in advance.

Nouns: cash advance, travel advance, preferred vendor, corporate rate, booking confirmation.

The traveler books through a preferred vendor at the corporate rate and may draw a cash advance for expenses that cannot go on a card. A Part 7 form shows the advance issued; a question about how much the traveler received points to the advance, not the total trip estimate. The trap offers the estimate as if it were the cash actually advanced.

Stage 4 — claiming the per diem

Verbs and collocations: claim a per diem, cover meals and incidentals, apply the daily rate, prorate the day, exclude non-reimbursable items.

Nouns: per diem, daily allowance, meals and incidentals, non-reimbursable expense, receipt requirement.

On the trip, the traveler claims a per diem — a fixed daily allowance that covers meals and incidentals without itemized receipts. A Part 7 question about whether a dinner receipt is needed points to the per diem rule: inside the allowance, no receipt; outside it, an itemized claim. Read carefully — a non-reimbursable expense like a personal upgrade is never covered, and ETS plants it among legitimate claims to test whether you know the boundary.

Stage 5 — reconciling on return

Verbs and collocations: reconcile the advance, settle the account, submit within, repay the balance, offset against.

Nouns: reconciliation, unused advance, balance owed, settlement, submission deadline.

Back at the office, the traveler reconciles the advance against actual spending: if the advance exceeded the costs, the balance owed must be repaid; if costs ran higher, the difference is reimbursed. A Part 7 question about what the traveler must pay back points to the unused advance, not to a cost the company already covered — ETS tests whether you can tell money owed to the company from money owed to the traveler. Note the submission deadline: a claim filed late may be denied regardless of the amount.

How ETS builds the traps

The linked set is almost always claim against policy. The report gives what was spent; the policy gives what is allowed. The question asks how much is reimbursed, and the answer lives where the two meet — the capped amount, not the full receipt. The trap offers the amount spent as if the whole sum were covered, ignoring the cap.

The second trap is the direction of the balance. On reconciliation, an unused advance is money the traveler owes the company; an overspend is money the company owes the traveler. The question asks who pays whom, and the wrong answer reverses the direction. Track which way the balance runs.

Practice the cluster in context

Read a travel request and its approval memo as one document, exactly as Part 7 presents them. Ask: what was approved, what does the per diem cover, and what must be reconciled on return? Then check each answer against the stage it belongs to — request, approve, book, advance, claim, or reconcile. The stage that answers the question is the only defensible choice.

For what happens after the trip — when every cost lands on a single claim form and moves through approval — work through the expense report and reimbursement approval cluster next, so the authorization and the reimbursement reinforce each other rather than competing for the same half-remembered word.

The cluster is small, fixed, and high-frequency. Learn the six stages as a loop, learn the collocation rather than the isolated word, and the travel-and-per-diem questions become some of the most predictable points on the test.
