Are 80 points less in the 10th standard

Calculate clef online, fully customizable18.01.2012, 22:19

With the clef calculator you can:
  • Define your own grading scale (or the grading scale of a specific country)
  • Calculate socketed clefs. Points or errors (e.g. vocabulary tests) serve as a reference value.
  • incorporate a "kink" (e.g .: How many billing points are there a 4?)
  • have the notes output in different gradations (tenths, quarters, thirds, halves, whole).
  • choose whether you want to award full or half points.
  • Calculate linear or IHK keys.
  • Download the clefs as CSV (Excel)

Tips for use

  • When you press the “Calculate” button, a table is output. There you can print them out using the print function of your browser (Ctrl + P on Windows) or download them for further processing in Excel by clicking on the corresponding link.
  • The option “tenth grades” is only recommended for higher maximum scores, as otherwise the jumps between the individual grades will be too large.
  • If you also award half points (e.g. for partially solved tasks), select the appropriate option.
  • When outputting the clef you can decide whether Tenth notes, quarter notes, third notes, or half notes are issued. Quarter grades are suitable for grading with “minus” and “plus” (1-, 3+, 3-4).
  • For Vocabulary tests use an error-note clef and output the notes as quarter or half notes.
  • The standard grading scale is 1 to 6 (Germany, lower and intermediate level). Adjust the values ​​as you wish.

Points-note calculator

You use this calculator if you know how many points you give the best mark in a class work / exam (example: "I will give a one with the maximum number of points of 40 points.")

What does "linear clef" mean?

The »normal« point-grade key calculates - in contrast to, for example, the Abitur or IHK variant - one linear key. If you get results that confuse you, read here: Full, Half, Quarter-Note Linear Clef: Spread or Round?


In the basic setting, the worst grade is given at 0 points. But you can also "base"Install:The “base” denotes the number of points that are before the best or behind the worst grade. So you might decide that you can get the best grade even if you haven't got the maximum number of points. Or you can decide that from 10% of the maximum number of points downwards you get the worst grade. To make the clef more human, install a base BEFORE the best grade (example: maximum possible number of points = 100 points, but the best grade is still 90 points). To make the clef more violent, add a base AFTER the worst grade (example: 10 points give you the worst grade, not 0 points).

Kink vs. linear

Perhaps you would like to set how many clearing points you get a sufficient grade. To do this, use the luxurious kink clef calculator. In the standard setting you get a linear clef calculator. For more details read here:

Point-grade calculator: Abitur key

No linear clef is used in the Abitur. The clefs differ in the federal states, although a standardization has taken place: In most federal states, the KMK standard key will be used from the Abitur 2021 at the latest, partly (e.g. in Baden-Württemberg) with slight modifications, see below. The definition of the KMK standard grading key for the upper level is specified here: Agreement on the design of the upper level and the Abitur examination (PDF), Annex 1 (p. 22)

KMK standard clef for high school and Abitur exams

Grade pointsat least the proportion to be achieved in the total assessment units to be achieved or in the overall performance (in%)

Abitur code of the federal states


From the Abitur year 2021 (i.e. the students who graduate in 2021 or later), the KMK code is used, but the KMK specification is interpreted very generously: In the 60 table, 16 credit points are already awarded 2 grade points , although mathematically it would have to be 1 grade point (16 of 60 = 26.66%; according to KMK guidelines, 2 grade points are only awarded from 27%). In Baden-Württemberg, half and more percentage points are generally rounded up (further explanations). That is why we offer a second rounding mechanism ("round up") in the standard Abitur calculator.

Until the high school graduation year 2020, different notation codes would be used - one for the non-linguistic subjects of the general high school, one for the vocational high schools and the linguistic subjects of the general high school. These computers were last used in summer 2020; we took them offline in August 2020.


... will also work extensively with the KMK standard key from 2020, see e.g. here (PDF).

The usual KMK key is also used in Brandenburg; the evaluation key can be found in number 6 of the administrative regulations for performance evaluation in the schools of the state of Brandenburg (VV performance evaluation) of July 21, 2011 (OJ MBJS / 11, [No. 5], p July 31, 2020 (OJS / 20, [No. 28], p.282).

The KMK standard notation is also used in Hamburg, see e.g. here: Hamburg: Abitur 2021 - Regulations for the central written examination tasks (PDF)

The KMK code is explicitly defined as binding, e.g. for the subjects of mathematics (p. 123), biology (p. 127), chemistry (p. 132), physics (p. 141) and computer science (p. 137).


From the 2019/2020 school year (i.e. the 2021 Abitur class following) the standard KMK key is binding in Hesse. This is regulated, for example, in the so-called anticipatory decree to amend the upper level and abortion ordinance (PDF).

Rounding is also explicitly addressed here: »The whole number, not rounded, percentage is used as the basis for determining the points.» (P. 4) - This means that (in the sense of the KMK table) a percentage of 26.9% is calculated as 26% (and not: 27%). See also the short synopsis of the anticipatory decree on the "sixth ordinance amending the Upper School and Abitur ordinance (OAVO)"

Until then (i.e. Abitur class 2020 and earlier), a modified KMK key is / was valid in accordance with the Upper Level and Abitur Ordinance (OAVO) of July 20, 2009 / April 4, 2013 (PDF), Annex 9a (p. 70).

Mecklenburg-Western Pomerania

In Mecklenburg-Western Pomerania, the KMK standard key will be used from the Abitur 2021, see e.g.

Until then (i.e. up to and including Abitur class 2020) a more moderate key will be used, see e.g. - preliminary information on Abitur 2020, general subjects (PDF)

A good overview of the Abitur procedures in Mecklenburg-Western Pomerania Advance information can be found on the website of the MV education server.

Lower Saxony

The KMK standard key has also been in effect in Lower Saxony since the Abitur examination 2017, see e.g. Lower Saxony Ministry of Education 13.02.2017: Written Abitur examination 2017 (PDF)

North Rhine-Westphalia

The standard KMK key is also used here. Grade points that are not whole numbers are generally rounded up at 0.5. See e.g. - Scheme and examples for the formation of grades in the Central Abitur (PDF)


In Saxony, too, the KMK standard key applies to the upper level and to the Abitur, see VwV Implementation of the upper level and Abitur examination of August 3, 2018 (MBl.SMK p. 478), which is governed by the administrative regulation of January 31, 2019 (MBl.SMK p. 34, 58) has been changed - Section VII, Paragraph 1, Point c "Evaluation Scales"


... also uses the official KMK notation according to RdErl. Of the MK from 26.6.2012 - 2-83200, changed. by RdErl. of the MB dated May 23, 2019 (SVBl. LSA 2019, p. 109). Incidentally, there is also a suggestion for the notation that is to be used outside of the qualification phase at the grammar school (grade 1 from 93%, grade 2 from 75%, grade 3 from 60%, grade 4 from 40%, grade 5 from 20%, until then grade 6).


The educational standards / uniform examination requirements of the KMK are decisive here (Education Schleswig-Holstein: Documents Abitur examination at general schools - Who has further information on which grading system is used for the Abitur? Please mail to [email protected]

Difficulty level of the Abitur clef

The spicy fact is that the evaluation keys used in the Abitur determine the level of difficulty of the Abitur. In the last few years the clefs in the individual federal states have often been different, but never more demanding than the KMK clef. In Hesse you always got one percentage point in the upper range until 2020, in Baden-Württemberg you got one grade point for 11% of the billing points in German and foreign languages ​​by 2020 (math + other subjects: 18%), in Bavaria, North Rhine-Westphalia and Saxony KMK-compliant only from 20%. Thanks to the comprehensive standardization to the KMK standard, this is now largely over.

Note that the Abitur code is quite tight in the lower ("worse") range - while a linear clef with 31 percent of the credit points would still take the 5-point pass, the Abitur code must contain at least 45 percent of the total possible credit points be. In return, the key to the top becomes a little slacker, with 95% of the billing points you get the best grade (namely 15 grade points).

You will find three calculators here: one with the KMK standard specifications, which will be applied in most (all?) federal states from 2021 at the latest, and two obsolete ones for the Abitur assessment in Baden-Württemberg (valid until the Abitur 2020, after which the KMK also applies in Baden-Württemberg -Computer),

Abitur calculator, evaluation key "Standard"

Use this calculator if you know the maximum number of points for your exam / class work and want to set high school graduation standards according to the standard specifications. Note the rounding mode there ("soft" for example for Baden-Württemberg or student-friendly rounding in detail, "strict" for the other federal states that implement the KMK specification).

The output is always given in whole grade points. A base is not possible.

Points-grade calculator, IHK key

The IHK code is usually used in conjunction with the German grading system (1 to 6). Use this calculator if you know the maximum number of points for your exam / class work.

The distribution of the grades is based on the IHK point and grading system, which is usually based on a 100-point scale. The IHK key is not linear (see picture) and much stricter than a linear grade-point key.

If you want to work with a different maximum number of points (than 100), adjust the setting in the calculator accordingly. The output is always in tenths of a note. A base is not possible.

Error grade calculator

You use this calculator when you know how many mistakes you give the worst mark for. This is the case, for example, with vocabulary tests.

You can also install a “base” here and, for example, give the best mark with 4 errors (and not with 0, as suggested in the basic setting).

Grading systems of other countries

If you need a clef that does not correspond to the German 1-6 system (which is almost unique in the world), you can make all the appropriate adjustments in the two calculators above, provided the grading scale is numerical (and not, as is common in the USA, for example , operated with letters A, B, C ...).

Here is a list of some other, mostly country-specific, grading systems. Most of the information is taken from the Wikipedia article School Grade. The WES International Grade Conversion Guide For Higher Education offers information for the grading systems of almost every country in the world, but in many cases these are incorrect or only cover the grade range in which the achievement is considered sufficient for passing.
