About this exam

The Perit Warrant Exam is the credentialing assessment for professionals who want to act as an expert in building appraisal, measurement and technical inspection - typically aparejadores, building engineers, architects técnicos and quantity surveyors working in Spain or in jurisdictions that recognise the peritaje tradition. It tests whether you can move between three worlds: the legal (contracts, liability, expert evidence, planning rules), the technical (structures, materials, installations, energy performance) and the economic (measurements, budgets, valuations). The exam is delivered in Spanish as a multiple-choice test, and the domains are weighted unevenly - construction law is the single largest block, so candidates who treat it as a formality usually regret it. Preparation should be built around the official programme published by the examining body, not around generic construction quizzes: read the applicable legislation in force, work through measurement exercises from real plans, and practise justifying a technical conclusion in writing. Because the syllabus references Spanish and EU norms that change, always confirm the current edition of each standard and the current exam regulations on the official body's website. Question counts, timing, fees and pass marks are set by that body and are published there; this page does not restate them.

What you'll study

Common questions

About Perit Warrant Exam preparation

What exactly does the Perit Warrant Exam qualify me to do?

It certifies that you can produce technical reports, valuations and measurements that stand up to scrutiny - for courts, insurers, communities of owners or contracting parties. The warrant is about defensible judgement, not just calculation, so expect questions where two answers are technically plausible and only one is legally correct.

What is the exam format?

Multiple-choice questions across nine weighted domains. The largest is construction law, followed by measurement and budgeting, construction technology, structures, installations, project management, urban planning, energy efficiency and professional practice. Confirm the current format, number of items and any penalty for wrong answers in the official regulations before exam day.

How hard is it, and where do candidates lose marks?

The technical questions are usually manageable; the losses come from legal precision. Candidates confuse contract types, misapply limitation periods, or answer planning questions from memory instead of the applicable regional rule. A second common failure is unit errors in measurement - mixing m² with m³, or forgetting waste and overlap factors in a budget.

Can I retake the exam if I fail?

Retake rules, waiting periods and any limit on attempts are set by the examining body and can change between sittings. Check the current call and the regulations on the official website rather than relying on what earlier candidates experienced. Plan your study as if you have one attempt, and leave time for a second sitting in your calendar.

How much time should I plan for preparation?

Most successful candidates spread preparation over several months, with the final weeks reserved for timed practice. Weight your hours to the domain percentages: law and measurement together are about a third of the paper. Reading legislation once is not enough - you need to retrieve the rule under time pressure, which only practice produces.

In what order should I study the domains?

Start with construction law and measurement, because they carry the most weight and frame everything else. Then technology and structures, which share vocabulary with measurement. Finish with installations, project management, planning, energy and professional practice. Revisit law at the end, once the technical context makes the legal scenarios easier to read.

Do I need to memorise standards and numeric tables?

You need working familiarity, not recitation. Know which standard governs which question, the order of magnitude of common values, and how to apply a formula. Examiners test judgement and application; a candidate who can reason from a principle usually outperforms one who has memorised a table without context.

How should I handle questions where I am unsure?

Read for the qualifier - 'always', 'never', 'only' - because absolute wording is often wrong in law. Eliminate options that mix two concepts, such as liability with warranty periods. If there is no penalty for guessing, answer every question; if there is, decide your threshold in advance and stick to it.

Where do I find the official dates, fees and pass mark?

Only on the official examining body's website and in the published call for each sitting. Those figures change and this page deliberately does not quote them. Save the regulations document locally, note the version date, and re-check it a few weeks before the exam in case the call has been amended.
