The situation that you report reveals a lack of coordination of the Pedagogical Council with the coordinators of course and cycle of studies. In my university, this situation would hardly occur because the timetable of assessments, once made, is sent by the President of the Pedagogical Council to the Students' Association and to the Course Coordinators, who have the duty to verify that there are no incompatibilities. It is only after this confirmation that the evaluation timetable is approved and made public.

However, this situation can occur if the student has curricular units of the study program of different years, for having failed. In this case, the students report the situation to the Pedagogical Council, which informs the teacher of the Curricular Unit, asking to propose an alternative date for the students to be able to do the evaluation.

Yes, this may be possible if they are assessed by two different Faculty member, or if their assessment may require different skills and competencies during the lab or class,subject to assessment metrics and outcome expectations.

In my university, this is the role, usually, student is evaluated with two examiners in the same time in different room for the same subject (one is internal and the other is external from another local university). The average of the two marks are taken for the student. This is more fair. 

When I say:

"Is it possible for a student to have two evaluations at the same time from different subjects that are from the same year and semester?",

I mean evaluations scheduled for the same period of time, or overlapping partially, but in different rooms, with different teachers, forcing the student to possess the ability of being in two different places at the same time.

The situation you describe is conflict of examination / test times. This can and does happen in practice. It should be avoided by publishing the timetables early enough for the student to spot and complain. For a typical form, see the link below.

It is the student's responsibility to report it early, and the university's responsibility to reschedule one exam / test. Neither party can shirk their responsibility.

If the student does not report it, the student gets zero for the unwritten exam / test. If the university fails to reschedule one, it is obliged to offer a supplementary exam / test.

You are right Ian Kennedy. We should stress, that it should be reported using a written form, so later the student can possess some kind of document that proves it was reported. If you only do it orally, you risk the other party won't "remember" you reporting it, refusing reschedule... Unfortunately, not all higher education institutions have these formal forms to secure both parties (student/ teacher or institution).

It should not happen. If it happens it is because there are problems in planning the evaluation of learning, which is the responsibility of the University.

In my university the professors propose at what moment to carry out the evaluations of the subject that they teach, later an analysis is made to avoid that coincidences occur and the definitive planning of the evaluations is made. There are people who are in charge of doing this work.

Due to human pitfalls, it can happen. Yet, to be fair to learners, swift arrangements must be made to sever the conflict in times and days for the evaluation. Such conditions are unethical in the academia.

it depends on the objective of this evaluation. it is the evaluator who decides on the feasibility of this method. in genaral nothing forbids it, but it remains a relative question.

Thank you for your answers. I agree with you Dickson Adom. In my opinion it's unethical.

Driss Harrizi you can't be in two different rooms at the same time... that's the problem. We are not talking about some kind of interdisciplinary evaluation, but of two different subjects that belong to the same curricular year and semester, whose evaluation moments coincide in time but have different locations in space...

I'm tempted to say that this would be extremely complicated to justify here in the UK in terms of QA. Saying that there are elements of synoptic assessment that could be used to support this so in theory a project could be used to assess two different components/modules, i.e. a learning outcome for a research component and a LO for the application component, or the design skill and the technical skill in an engineering project. I wouldn't say it is unethical but difficult to justify and especially difficult to explain to students.

Thanks for your contribution Diogo Casanova, but this question is about students who have evaluations from different subjects at the same time. For example, you can't ask a student to do on the 15th March 2018 the English 1 exam on room 1 at 10 a.m, and to do in room 3, Enlish Literature 1, also at 10 a.m. This is what is being discussed. Institutions should have strict rules against it. This is unethical. The student can't be in two different places at the same time.

The situation that you report reveals a lack of coordination of the Pedagogical Council with the coordinators of course and cycle of studies.

In Cuba we have the main professor of the academic year. He is a professor who is in charge of coordinating the fulfillment of the evaluation and the educational policy in general. In this way, a better level of planning of all the training actions that are exercised on the professional future is achieved. This system is giving us very good results in the permanence of students in their universities and above all in the quality of their training, as they receive personalized attention. The main teacher of the year builds more orderly educational influence mechanisms among all the teachers who work with the same group of students.

Thank you for your answer Herculano Cachinho. I am just going to repeat that a reporting form should be created to protect the student. Or that the student or researcher should always use the written form to report the situation. Unfortunately, at some portuguese institutions calendars and emails rescheduling exams aren't enough... they just prove they happened at the same time and they may accuse you of not reporting within the due dates and refuse to act. Never do it orally even if you are a researcher at the institution and discussing it among work colleagues. Also, refuse any meetings where a written report with the date, subject matter discussed and resolution is not written and signed by both parties. Emails scheduling a meeting only prove that a meeting was scheduled.

Reinaldo Requeiro, I also thank you for your answer. It seems a good system, where you show concern about the students' achievements.

it will be injustice if student's papers are scheduled in a way that he has to appear in two papers at the same time or after very short period of time. it will effect negatively on the progress and results of student. There must be flexibility in the system to facilitate students for healthy learning system.

I agree with you Ajab Ali Lashari.

I agree with Prof. Kennedy and Bro. Dickson's contributions.

I would not recommend it.

it depends on the objective of this evaluation and the subject.

Yes, it can happened

Ola Adel, thank you for your contribution but we are not talking about interdisciplinary evaluation, but discussing conflict of examination / test times. You can not be in different places at the same time.

Ahmed Mahdi, you are right, it may happen, but if it does it should be immediately corrected.

Borden Mushonga I agree with you, and it raises ethical issues.

Harry Barton Essel I also agree with them, but I stress there should be an online form or some other process, where the student is able to prove that he/ she has reported it, namely for legal purposes.
