Frequently asked questions

Diplomas & Academic Records & Transcripts

What is diploma recognition?

Diploma recognition is the alignment of Lithuanian and foreign education. In order for you to be accepted for study in Lithuania, your previous education needs to be evaluated against the Lithuanian degree structure.
The acknowledgement of the applicant’s education documents is performed by the University under the procedure set out by the University. More information is available at academic-recognition.

How do I know if you recognize my degree?

You will be informed by email about the results of recognition within ~1 month.

When we receive documents required for the recognition of qualification, the process of your foreign degree documents evaluation and recognition will be started.

More information about important dates here: Dates and deadlines

Can I apply with my temporary (provisional) Master's diploma issued abroad?

For the admission process you have to submit your final degree diploma, a temporary (provisional) degree certificate is not accepted.
A temporary (provisional) degree certificate is a document issued by an institution to a student who has been awarded or conferred an academic degree. The temporary (provisional) degree certificate is issued as a replacement for the actual degree certificate e.g. in case the actual degree certificate cannot be given to the student immediately after the studies have been completed due to technical or administrative reasons. As far as all foreign degree diplomas must be evaluated and recognized, only final certificates are processed, and therefore any temporary / provisional diplomas will be considered as insufficient for final evaluation and recognition.

For admission there is a requirement to provide Master's Diploma and its supplement only. Why am I asked to provide documents of my Bachelor studies as well?

If your Master’s diploma was issued outside Lithuania, then according to the regulations it must be evaluated and recognized. For diploma recognition process both Bachelor and Master diplomas and their supplements are mandatory.
More information is available on KTU Academic Recognition

My MSc (BSc) is issued abroad. Do I have to get it translated / apostilled / certified / notarized?

All Master’s degree documents issued in languages other than English or Lithuanian should be supplemented with an official translation.

All documents (original language and translation) necessary for the evaluation must be officially certified!

The certificates in original language must be notarized. A simple copy, attached to a certified translation, is not enough.
The translated documents must be officially certified or stamped by the translator

Usually, a translation contains, in addition to the translation, a copy of the certificate in original language. However, translators are only allowed to certify the document issued by themselves. Take both the translation and the original certificate with you to the certifying authority. By this you can ensure that both documents (translation and document in original language) can be certified.

Do I have to list all the schools and institutions I have attended?

It is required that you list all post-secondary institutions you have attended: you need to list details about your both Bachelor’s and Master’s studies (and PhD, if applicable). If you are currently pursuing your PhD research, you must also indicate that information.

My name in my official transcripts is different from my passport/other transcripts; shall I provide a document explaining the discrepancy?

Yes, in such cases is required to provide a notarized name change certificate.

What should I do, if I receive my Master's diploma later than the application deadline?

Provided that your studies are in Lithuania, Latvia, Estonia, and if the Graduation Ceremony is later than the application deadline, you should contact the your Faculty/Academic Office with the request to issue:
– a document certifying the fact that you have completed certain Master programme, and the date of diploma awarding must be indicated;
– an academic transcript of all study semesters in that Master programme, including credits and evaluations, as well as the results of Master thesis defence.

Additional supporting documents

I am asked to submit two recommendations. What must be included in the document?

The recommendations have to be issued in the same calendar year when the candidate’s application is submitted. Therefore, if you are applying in 2024, the recommendation is considered valid if issued in 2024.

A recommendation must explicitly specify the institution and the doctoral programme to which the candidate is being recommended. That means, that the refereee should clearly indicate that he/she recommends you for PhD studies in, for example, Informatics Engineering, at Kaunas University of Technology.

The supervisor of the topic is not responding to my email, and I cannot get the recommendation. Can I still apply?

In such case, for those programmes where it is mandatory to provide a recommendation by the supervisor of the topic, your application will be considered as incomplete and will be withdrawn from the competition.

According to the Admission Regulations recommendations by two scientists representing the relevant science field (a recommendation of the supervisor of the topic to which the applicant is applying is required in the science fields specified in Appendix 2 to the Regulations; if the applicant is applying to the positions of doctoral studies funded under the invitation to doctoral studies under the competition of the Research Council of Lithuania, a recommendation of the supervisor of the topic to which the applicant is applying is required). The recommendations have to be prepared in the same calendar year when the applicant’s application is submitted. A recommendation has to clearly specify the institution and the science field to which the applicant is being recommended.

What is a consent of a supervisor of the research topic and how should I get it?

A consent of the supervisor of the topic to which the candidate is applying to Informatics Engineering is required to confirm that the supervisor agrees to supervise the candidate if he/she is invited to studies.
That means that a candidate has to communicate with that researcher (future supervisor) well before the application deadline.

What is a list of publications?

A list of the research works has to be submitted with the unabridged bibliographic description. You may search the internet on “bibliographical references on a list of references” to see what it looks like.

Can I submit my documents as pictures ( .jpg, etc.)?

No, only PDF format is acceptable.
Failure to follow the requirements may result in rejection of application.

For the programme that I am applying it is required to provide a research proposal. Is it the same as research paper?

No, research proposal ≠ research paper.

Note! 2 topics = 2 research proposals, that means if you choose two different topics in the programme that requires research proposal, you will have to write two different proposals, for each of your chosen topic.

How to write a research proposal: Admission regulations Annex 5

I do not have any paper published yet. Am I eligible to apply?

Yes, you are eligible apply to all programmes offered by KTU except to Informatics Engineering: for this programme at least one publication is mandatory.

In this case you will have to write a research paper on the topic that you are applying to. If you choose two different topics, you will have to write two different research papers for each of your chosen topic.

How to write a research paper: Admission regulations Annex 4

Where do I get the document certifying my English language proficiency?

If there is no English level indicated in your MSc or BSc diploma supplement, register for a test and obtain your certificate at:
– KTU Centre of Foreign Languages
– any institution, certified to provide this service

It now possible to document your English through the TOEFL IBT Special Home Edition Test. The test is a possibility for students to take their test at home rather than at a test center.

Can I send my English test result after the deadline for submitting supporting documents?

Unfortunately no late documents or test results are accepted.

Application fee

Can I pay my application fee after I am accepted?

No, all mandatory documents (including copy of application fee transfer) must be submitted by the application deadline.

I was not admitted during the main admission, but now I want to apply for additional admission/another PhD programme. Do I have to pay the application fee again?

Yes, as far as another admission process starts, you have to pay application fee again.

Eligibility & Requirements

I want to study either Chemistry, or Physics. Can I apply to both?

Yes, you can if you meet the requirements for both programmes. However, consider:
-the mandatory recommendations of supervisors
-your scientific experience in both science fields
-participation in interviews with each committee
-your motivation

I have MSc in Management, but I want to pursue the doctoral research in Mechanical Engineering. Am I eligible to apply to PhD in Mechanical Engineering?

You are eligible (provided that you have certain background and scientific experience in Mechanical Engineering, Technological Sciences).
After admission: possible necessity to take additional courses in the field of science (fee-paying).

Results of admission

My final competition score exceeded minimum required score. Does it guarantee admission?

No, the minimum required score does not guarantee you a position.
A certain number of state-funded positions can be less than the number of candidates with >min.competition score.
