I. THE ELEMENTS OF PhD EDUCATION
The PhD program is running according to individual curriculum. This curriculum is formulated in a
negotiating process between the PhD student and the institutional roleplayers, the thesis supervisor, the
department head, and the president of the partial program. This has to be approved by the Educational
Committee of Doctoral Studies (DTB) and the Council of Doctoral School (DIT). The educational and
research plans elaborated for each semester of the studies makes an integral part of the Work Plan.
The most significant part of the individual research work done in the advertised topic of the Doctoral School
makes the core part of the program. Each PhD student has one and only one supervisor at a time who is fully
responsible for directing the studies, the research and the degree preparation of the PhD candidate working
on the designated topic. It is possible, however, to approve dual supervision in studies based on international
cooperation, alternatively, in interdisciplinary topics accepted by the DIT, and with advertised topic
description with the preliminary approval of the University Habilitation Committee and Doctoral Council
(EHBDT).
In other cases (e.g. external topic supervision contracted with the Doctoral School) the DIT would nominate an
internal supervisor to follow and assist with the professional progress of the candidate on behalf of the
university.
During doctoral training at the Faculty of Mechanical Engineering the students concerned cna mainly choose
from among the course offer of the Faculty. The pool of the course offers can be widened with that of other
faculties, occasionally of different universities of technical science after the preliminary approval of the vice-
dean in charge of scientific affairs.
Directional education makes part of the training and and is mandatory to take. In the frames of it lecturing
abilities ands skills as long as communication skills get developed under the guidance of a designated
teacher. The subject, and credits associated with the course concerned, is identified by the head of the
supervisor’s department in accordance with the supervisor; the accomplishment is acknowledged by the
department head following the recommendation of the desinated teacher.
In the doctoral training 240 credits have to be obtained as follows.
a.) 30-50 credits – acquiring mandatory studies,
b.) 190-210 credits – scientific research work or creative artistic activity, directed educational activity.
According to the curriculum of the Faculty of Mecahnical Engineering PhD credits are shared as follows. 30 credits: acquisition of study materials 140 credits: scientific activities max. 46 credits: publications max. 30 credits: lecturing, assisting the teaching process

The principles of a PhD student’s curriculum are as follows.
a) Requirements of taking courses are concentrated in the first passage of the training program, thus,
providing the possibility of the most possible time to do research work from the 3rd year of studies.
b) Subjects with global exam requirements are two-semester long. From among these will be identified
those two the candidate has to sit a complex exam for at the end of the 4th semester.
c) On condition that the candidate has not accomplished them yet, any of the offered compulsory elective
may be chosen in the 2nd and 3rd semesters
d) The requirements of Individual research are quite decent in the 1st and 2nd semesters, however,
reserach on literature and its evaluation is mandatory, while the rest two semesters, 3rd, 4th are
already research-focussed.
e) The aim of Teaching activity is to acquire, with the assistance of a well-experienced lecturer, the
methods of how to develop teaching materials, to convey knowledge orally, to get to know up-to-date
teaching techniques, and to prepare measurement practice. Only character building activities directly
associated with teaching belong to this passage. The evaluation of the accomplishment, after
consulting with colleagues working together with the PhD candidate, is made by the department head
concerned.

f) According to the curriculum of the training and to the Code of Studies and Examinations of BME
(TVSZ)
- earning min. 20 credits per semester is mandatory,
- earning max. 45 credits per semester cannot be exceeded,
- research credits canot be summarized,
- credits to be earned in education cannot be substituted by research credits,
- by the end of the 2nd semester, according to the TVSZ, 50 credit points have to be accomplished,
- by the end of the 4th semester min. 120 credit point are to be earned,
- Publication I-II. subjects are to be accomplished by the end of the 4th semester.
g) The credit points of publication activities by no means can be separated, and can only be acknowldged
if the folowing criteria are met.
- Publication I earns credit for the candidate only if they either have produced a professional article or
a conference article in English by the end of the 3rd semester.
- Publication II earns credit for the candidate only if they have met the timely publication requirements
by the end of the 2nd year, when complex assesssment is scheduled, necessary to start the degree
seeking process; namely they have already written 2 already published or accepted articles for
publication, written in English.
- Publication III earns credit for the candidate only if the publication requirements necessary to start
the degree seeking process are at least met, and the candidate has accomplished the publication level
required.
- Publication IV earns credit for the candidate when his totally earned credit number reaches up to 34,
and has already met the minimum requirements of degree seeking.
h) The accomplishment of Individual research and Publication I-IV is certified by the supervisor of the
project. When there is external supervision there, a written assessment from the supervisor serves as
basis to the internal supervisor to accept and certify the accomplishment.
i) Absolutorium certifying the successful accomplishment of the PhD training can be issued when
Publication III has been completed and the totally collected number of credits reach at least 240.

I I I . REPORTS AND WORK PLANS
Reports
The interim reporting of PhD students goes according to local routine. The supervisor presents information
on it in due course. There is also a mandatory oral report on research at the end of the 4th semester, in the
frames of the complex exam. This particular exam has to be taken in front of a committee open to the public.
The committee has at least 3 members; and min. one-third of them can not be legally employed by the
institution running the doctoral school. The presidency of the committee can onlybe committed either to a
full professor, a Professor Emeritus or a researcher/lecturer with the doctor of the Hungarian Academy of
Sciences title. Each member of the committee helds a scientific degree. The supervisor of the examining
students, by no means, can be the member of the committee.
The complex exam has two major parts: in one the theoretical preparedness (theory part) is being measured,
while in the other the examinee gives and account on their scientific/artistic advancement (dissertation part).
In the theoretical part of the complex exam the examinee takes exam at least in two subjects/categories; the
list of these can be found int he educational plan of the doctoral school. The theoretical exam may also have a
written portion. In the second part of the complex exam, in the form of a presentation the examinee gives an
account on their acquired knowledge of relevant technical literature, research results. Further, the examinee is
to present the research plan prepared for the second part of the doctoral studies, respectively, the detailed
schedule of preparing the dissertation and the dissemination of results in publications. The supervisor should
be given the opportunity to, preliminary in writing, or maximum at the exam, prepare an assessment on the
examinee.
The examination committee evaluates the theoretical and the dissertation parts of the exam separately.
Minutes are taken with written evaluation in about the complex exam. The very same day of the oral exam
the result of the exam has to be announced. The complex exam can be qualified successful if the majority of
the committee members judge both parts of the exam a success. Failure in theory can get an extra repeat
exam int he very same exam period on the incomplete subject/s. If the dissertation part proves to be a failure,
this cannot be repetaed in the same exam period.
Written reports are to be prepared by semester on the accomplishment of subjects, the advancement of
research work, likewise about the publication activities of the given time frames.
Those PhD students whose reports clearly reveal deficiency and default will be given a notice by DTB, and
obligate to submit a more detailed report of 2 or 3 pages. In the report the following has to be recorded
- original goal and expectable new scientific results,
- scientific work done so far,
- the estimation whether, if at all and when, the original goal, including publication requirements
can be reached by the candidate.
- The report will be evaluated by the professionally competent member of the Doctoral Study
Committee (DTB). Further, the Council of the Doctoral School (DIT), considering also the
oppinion of DTB, decide on possible modifying or rescheduling of the program.

Work Plans
According to the Academic Rules and Regulations of BME a Work Plan has to be elaborated by PhD
students. However, in the cited document there is no set requirements as regards contents or formal elements.
DIT finds it necessary to set the principles and requirements of Work Plans.
Tasks can be divided into 4 major parts (see chart above):
- education (and associated exams in items 1, 2 and 3),
- independent scientific research work (item 4),
- publicizing research results (item 5),
- teaching activities (item 6).
Two Work Plans are expected by the Dean’s Office from the PhD students.
- right after their having been accepted for a PhD program, at the beginning of their related doctoral
activities, a full Work Plan for the full, 4-year duration of their studies has to submitted,
- another semester Work Plan is also a must at the beginning of each semester started. (This also refers
to students recently registered.)
The major aspects of preparing Reports and Measurements are as follows:
Work Plan for 4 years
Work Plan is to elaborate and schedule activities to be done during studies; also, to present aims and
recommendations associated with the below described three elements.
a) Education plan.
The Academic Rules and Regulations should provide a solid basis for the Education Plan, with special
regards on the appropriate share of basic, comprehensive exam and elective courses. The opinion of the
supervisor, as a default, has to be clarified when working on this document.
b) Scientific activities.
Beside providing an overall description of the research plan, in this document it has to be made clear what
pace will be followed in elaborating the chosen research topic, and also, the expectable scientific results
should be identified.
c) Teaching activities.
This is importnat to know that the educational activities of a candidate, by no means, can only be
calculated by the number of the independently given lectures, but also the preperatory hours spent on the
subject matter, further, consultation, preparation, and cooperation associated with other classes of the
department concerned.

Mid-Term Report
The ease the administrative obligations:
a) On condition that the educational and elective tasks detailed in the Work Plan for 4 years, referring to this
fact is satisfactory. Publication activities though are much accentuated that have to be detailed by
authors’s names, location of issuance, number of volume, page numbers, etc.
b) As regards research work, more detailed report on the previous semester has to be prepared, since the
original Work Plan for the 4 years focussed exclusively on planned activities and not on their results.
Once the scheduled educational and elective tasks of the previous semester work plan have been
accomplished, pointing these out would suffice the requirement.
Semester Work Plan
a) As regards the semester work plan to be submitted for the following academic period, if there is no
modification of these compared to the overall Work Plan for 4 years, only this fact has to be laid down.
b) It is mandatory though to submit a detailed work plan for research activities. When these goals have been
met, it is simpler to prepare also a report concerning the following semester.
The Report and the Work Plan have to be submitted electronically and in one printed copy. The latter
document has to be signed by the student, the supervisor, the Department Head, and the President of the Sub-
Program.
Tasks associated with the aforementioned have to be set int he Work Plans together with plans for obtaining
missing or inadequate language proficiency. Forms of Work Plans can be downloaded from the home pageof
the Doctoral School.
