Record marks,
report grades worked out

Tabula is a mark management program for teachers. The teacher enters the marks. Tabula proposes the report grade and shows every step of the calculation. All data is stored encrypted on the teacher's own computer.

02

Working out report grades

Tabula makes a proposal. The teacher makes the decision.

  1. 01

    Calculation on view

    Next to the proposal are all pieces of work, their weights and every step of the calculation. If something is missing, Tabula says so and does not calculate.

  2. 02

    Rounding once

    Tabula rounds only at the end. The intermediate results stay exact.

  3. 03

    Missing work

    A missing piece of work does not count as a fail. Excused and exempt are left out. For “not submitted” or a pending re-sit, the teacher decides.

  4. 04

    Confirming

    A report grade only counts once the teacher confirms it. If it differs from the proposal, Tabula stores the teacher's reason.

  5. 05

    Weighting

    The teacher sets the weighting. Templates for some German states are included. They follow the regulations but are not officially checked.

  6. 06

    Students joining or leaving

    Tabula takes into account when a student joined or left the course.

03

Data on the teacher's own computer

Tabula stores all data encrypted on the teacher's computer.

Password and key

The data is protected by a password. If it is lost, the recovery key helps.

Nothing is sent

Marks and names do not leave the computer.

Daily backup

Once a day Tabula creates an encrypted backup. It keeps the last 14 and the first of each month.

Automatic lock

After ten minutes without input, Tabula locks itself. The password is then needed again.

Readable without Tabula

An included reader script opens the data even without Tabula.

Without the password and the recovery key, the data cannot be opened. The exception is emergency access, if the teacher has switched it on. So print the recovery key and keep it away from the computer.

04

Emergency access

Emergency access helps when the password and the recovery key are both lost. It is switched off by default.

  • Switching it on and off is up to the teacher alone, at any time in the settings.
  • In an emergency Tabula shows a request code. The teacher sends it to Timo Britz.
  • Release: Timo Britz checks the person's identity and sends a release word. It works only once.
  • Afterwards the teacher chooses a new password and receives a new recovery key.
  • No student data: The code contains no names or marks. Without it, Timo Britz cannot open anything.
  • Check first: Emergency access is a third way into the data. The teacher checks with the school whether it is allowed.

Details are in the terms of use and in the privacy policy.

Settings in Tabula: emergency access is switched off.
Emergency access: switched off by default.
05

Data protection and schools

Whether student data may be processed on a teacher's own device is decided by the state and the school. Tabula does not make this check.

Description for the head teacher

At the press of a button, Tabula creates a PDF for the head teacher. It describes which data is processed and how it is protected.

Timo Britz receives no student data. A data processing agreement is therefore not needed.

In everyday school life

Built for one teacher on one computer.

  1. 01

    Mark table

    Marks are typed straight into the table. The class list comes from a CSV file.

  2. 02

    Names such as Nguyễn, Łukasz or Ayşe are printed correctly. If the font lacks a character, Tabula says so.

  3. 03

    Sheets as PDF

    Report grade sheet and mark list as PDF, one page per student.

  4. 04

    Export

Not yet included

Grading scales for single tests, absences, conduct grades, seating plan and mark statistics.
