Complete Guide to Replacing a Lost École Polytechnique Diploma (For International Students)

Introduction

For international students who completed their studies in France, the diploma from École Polytechnique is not only the proof of years of hard work, but also a core document for academic credential verification, job hunting, household registration, and further education after returning to China. However, accidents happen — École Polytechnique diploma replacement after loss is a tricky problem many international students face after graduation. If you are searching for “how to replace a lost École Polytechnique diploma,” this article is for you. Based on common practices in French higher education, official École Polytechnique policies, and the requirements of the Chinese Service Center for Scholarly Exchange (CSCSE), we have compiled a clear, credible, and actionable replacement process to help you avoid being misled by intermediaries promising “original diploma replacement” or “express issuance,” and restore the validity of your academic credentials in the shortest time possible.

1. Why Must You Act Quickly If Your École Polytechnique Diploma Is Lost?

Losing your diploma is never a minor issue. For international students planning to return to China, it directly affects three major matters:

1. CSCSE credential verification: Without the original degree certificate, your verification application may be rejected or require additional proof.

2. Job hunting and household registration in China: Many employers and first-tier city household registration policies require a credential verification report, which is based on the original degree certificate.

3. Further education: Applying for a PhD, MBA, or other advanced programs usually requires proof of your previous degree.

Therefore, once you discover that your diploma is lost, starting the official replacement process as early as possible can reduce time costs for subsequent verification and employment. French universities are known for slow administrative processing, especially when archive retrieval is involved, often taking weeks. Do not delay.

Key Note
French higher education institutions generally do not reissue original diplomas, but official documents such as “Attestation de réussite” or “Attestation de diplôme” (degree certificate) are usually accepted by the Chinese Service Center for Scholarly Exchange for credential verification. In other words, your goal is not to “get the same piece of paper back,” but to “obtain an official replacement document with verification validity.” This article also serves as a practical guide for international students on replacing lost French degree certificates, so be sure to bookmark it.

2. First Understand: Can École Polytechnique Reissue an Original Diploma?

2.1 Common Practice in French Universities: No Original Reissuance, Only Official Attestations or Certified Copies

Unlike Chinese universities, most French universities and engineering schools do not provide a second original diploma. The original diploma is usually produced only once; once lost or damaged, the school will not reprint a certificate with the original seal and president’s signature. However, this does not mean there is no remedy. The school’s academic office (Service Scolarité) or diploma office (Bureau des Diplômes) can issue official documents, such as:

• Attestation de réussite: Proves that you have passed all academic requirements and graduated.

• Attestation de diplôme: Proves that you have obtained a certain degree, usually including the degree name, major, year of award, and signature of the president or registrar.

• Copie certifiée conforme: A certified copy of the degree certificate, with legal effect close to the original.

2.2 Difference Between “Attestation” and “Original Diploma” and Their Legal Validity

In France, “Attestation de diplôme” is a formal document recognized by the government and education authorities to prove degree holder status. In the CSCSE credential verification process, if the original is lost, you can submit such an official document issued by the school along with a personal statement. Therefore, the core of École Polytechnique diploma replacement after loss is to obtain this official document with verification validity, rather than insisting on a “new original.”

Expert Tip
When writing to the school, do not use expressions like “reissue the original diploma,” which may cause misunderstanding. Instead, clearly request “délivrer une attestation de diplôme” or “fournir une copie certifiée conforme.” This reduces communication barriers and avoids being rejected by the school on the grounds that “original diplomas cannot be reissued.”

3. École Polytechnique Diploma Replacement: 4-Step Official Process

The following steps are based on current École Polytechnique policies and common practices in French higher education, i.e., the École Polytechnique diploma replacement process. Please refer to the latest information on the school’s official Service Scolarité page.

3.1 Step 1: Prepare Personal Identity and Academic Information Materials

According to school requirements, you need to prepare the following materials:

• Student number (Numéro étudiant) or enrollment number (can be found in old emails, transcripts, or diploma copies)

• Year of enrollment, year of graduation, full name of the program (in French, e.g., “Diplôme d’ingénieur de l’École Polytechnique”)

• Déclaration sur l’honneur de perte: a written statement in French explaining the time, place, and circumstances of the diploma loss, signed and dated

• If entrusting someone else to handle the process, a power of attorney in French (Procuration) and the agent’s identification

• If the diploma was stolen, it is advisable to attach a police report receipt (Récépissé de dépôt de plainte) to expedite review

Key Note
École Polytechnique may require some paper materials, especially signed statements, to be submitted by mail. It is recommended to first confirm with the academic office by email whether scanned copies are acceptable.

It is recommended to use the official forms published on the school website and avoid intermediaries or unofficial links.

• The type of document requested: Attestation de diplôme or Copie certifiée conforme

A simplified French email template:

Objet : Demande d’attestation de diplôme suite à la perte du document original
Madame, Monsieur,
Je suis ancien(ne) étudiant(e) de l’École Polytechnique, promotion [year], filière [major]. Mon diplôme original a été perdu. Je vous prie de bien vouloir me délivrer une attestation de diplôme officielle, ou une copie certifiée conforme, afin de me permettre d’effectuer la reconnaissance de mon diplôme en Chine.
Vous trouverez ci-joint une copie de mon passeport et mes informations d’identification.

Graduation certificate, diploma, transcript, educational background, academic certification, production and purchaseThe exact amount and payment method should be subject to the school’s reply. Never pay high “expedited fees” to any “intermediary,” because schools generally do not speed up processing for third-party agents.

3.4 Step 4: Simultaneously Handle CSCSE Credential Verification or Return Certificate

After obtaining the official document from the school, you should immediately initiate or update your CSCSE credential verification. According to current CSCSE regulations, if the original diploma is lost, you can submit an official attestation issued by the school along with a personal statement explaining the loss. This involves a key long-tail keyword: École Polytechnique degree certificate loss verification.

Meanwhile, if you plan to return to China for employment or household registration, you may need to check whether a “Certificate of Returned Overseas Chinese Students” is required (some countries have abolished it, but some Chinese cities still require it). At this point, you may encounter the question of what to do if you are missing materials for overseas study verification after returning to China. It is advisable to confirm with CSCSE customer service or local talent service centers in advance to avoid rejection due to incomplete materials.

4. FAQ: École Polytechnique Diploma Replacement

4.1 How to Replace a Lost École Polytechnique Diploma and How Long Does It Take?

“How to replace a lost École Polytechnique diploma” is a question many international students care about most. The core path is to apply for an official attestation from the school’s academic office. According to École Polytechnique’s official processing speed, it usually takes 4 to 8 weeks from the time the school receives complete application materials. If archive retrieval is involved or paper attestations need to be mailed, the time may extend to more than 10 weeks. It is recommended to start the replacement process at least 3 months in advance to avoid affecting CSCSE verification and return arrangements.

4.2 Can Someone Else Handle the Process on My Behalf While I Am in China?

Yes. Most French universities allow authorized representation, but you need to provide a signed power of attorney in French and a copy of your passport. The power of attorney can be self-written without notarization, but the format should be formal. It is recommended to first confirm by email whether the school accepts representation.

4.3 Will the Official Attestation Issued by the School Affect Domestic Credential Verification?

Generally not. The core of CSCSE verification is to confirm that you actually obtained the degree. As long as the school issues an official attestation that clearly states the degree level, major, and award date, the verification pass rate is very high. However, it is recommended to attach a personal statement explaining the loss of the original to avoid reviewer questions.

4.4 Is There a Fee for Replacement?

Some schools waive administrative fees, while others may charge a small amount (e.g., €10–50) for certified copies or international postage. All fees should be paid through official school channels. Never transfer money to personal accounts.
