3G random checks model test

With random checks of the 3G access requirements for courses, the University of Ulm is pursuing the goal of enforcing the regulations and at the same time reducing the effort for the checks to a reasonable level. In addition, the vaccination rate among students is to be determined. At the University of Ulm, the control of the 3G access requirements to courses is carried out by the lecturers, who are also responsible for the compliance with the hygiene regulations in their courses.

FAQ 3G random checks model test

The population for the model project under consideration is the number of face-to-face courses reported per week. The aim of the pilot project is to derive valid estimated values from the defined population in the sense of sampling that is as representative as possible. In order to minimise the additional effort on the part of both the lecturers and the students, the aim is to check at least 5% of the weekly scheduled face-to-face lectures. Accordingly, the academic support of the model project will carry out a weekly sampling and notify the responsible teachers.

The overall aim of the accompanying scientific research is to emphasise the current regulation that face-to-face teaching is only possible if the 3G rule is fulfilled. The random checks should be carried out with as little effort as possible for both sides (students and teachers).

The participants of a course include all persons who are involved in it. In addition to the students, this also includes the teachers, assistants and technical staff involved.

Yes, all participants must meet the 3G requirements.

The teaching staff will check the participants' 3G certificates at the entrance to the event room. Persons without a valid 3G certificate must be excluded from the event. No identification of persons will be made during the checks, only the types of proof will be counted.

  • A complete vaccination certificate (e.g. vaccination certificate with 2nd vaccination since at least 14 days, digital vaccination certificate, official vaccination certificate),
  • a certificate, e.g. issued by a general practitioner, confirming that a covid infection was overcome no more than 6 months ago,
  • a negative rapid test at a test station specially commissioned for this purpose in accordance with § 6 Paragraph 1 of the Coronavirus Test Ordinance of 21 September 2021 (BAnz AT 21 September 2021 V1) (citizen test centre, pharmacy, GP or similar), which is not older than 24 hours at the start of the event, or a negative PCR test certificate which is not older than 48 hours at the start of the event.

Persons without such proof are excluded from participation in the event. A negative test carried out by a non-certified testing facility under supervision (employer, association, other university or similar) cannot be used for admission to other facilities or events.

For employees, the self-test issued twice a week by the university is also valid as proof of testing. They must document their negative test results.

When counting, you take into account the 3G certificate that people show when they are checked.

Persons without a valid 3G certificate are excluded from attending courses. Kindly point out that the course may not be entered. In most cases, those wishing to participate will simply have forgotten their certificate and can present it at the next course date.

If people without a 3G certificate refuse to leave the room when asked to do so, police assistance can be requested from the caretakers of the University of Ulm. The number can be found on the user instructions posted in lecture halls and seminar rooms. As a lecturer, you are initially acting within the scope of your domiciliary rights. This allows you to prohibit a person from entering the event room for the duration of the event. You only need to call in the caretaker or security service if the person does not comply with this instruction (see Hausrecht.pdf). Participation in an event without a 3G certificate is a misdemeanour, see § 11 CoronaVO Studienbetrieb. Attempting to participate is not a misdemeanour if it is already rejected at the entrance to the event.

  • The teachers of the courses selected in the weekly sample are informed by e-mail via 3G-Stichprobe@uni-ulm.de in the week before the selected course date that they have to carry out a full check of the 3G evidence of the participants in the selected course on the selected date. The Dean of Studies will also be contacted with his/her personal email address to inform him/her about the 3G sample check in his/her own subject.

With the e-mail, the teachers receive a data entry form in which they make the following entries:

  1. Usually expected number of participants at the event date.
  2. Number of participants with
    • a. Proof of vaccination
    • b. Proof of recovery
    • c. proof of testing
    • d. Without proof
  3. Time required for the control
  4. Number of persons employed for the control
  5. Free text comment

Checking is done by the teachers at the entrances to the room in which the course takes place. This can also involve several rooms if several parallel appointments are scheduled at the same time. The 3G records are checked without identifying the persons. Only the numbers of certificates in the four categories: vaccinated/tested/genetically tested/no certificate are recorded. Lecturers who are also considered participants in their course also record their evidence in one of the above categories. It is not possible to link the type of evidence with the name of the participant.

We would like to find out if the number of actual participants is very different from the expected number. There can be many reasons for this, including the way 3G is assessed at the university. For example, if you have 15 participants in a small seminar and then "only" 12 are present in the sample, this could be related to the review. We plan to show these effects and possibly investigate the effect on the rate estimate under certain assumptions. Therefore, we would be interested in expected student numbers in the courses that are as realistic as possible.
