Wikidata:Property proposal/grading system
grading system
editThis property was requested after extensive consultation with the Wikidata community and experts on ed tech, OER, global and national curriculum, education policy, and digitization. Over the two rounds of the consultation, we received input from 31 individuals representing various global perspectives and areas of expertise to aid in the full implementation of the Wikidata for Education project.
Originally proposed at Wikidata:Property proposal/Generic
Description | The value indicators used by educators to evaluate the performance of the pupils in exams on the standard particular scales which is based on the points entirely and consist of the grades like A-F or range like 1-10 |

Motivation
editThis property will be used to specify the grading system that is used for curriculums of specific educational systems. Some educational systems use alphabets-letter grading system (A or A+ for gce) for grading while others use numbers-Numeric grading system (grade 1 for BECE) and others combine alphabets with numbers numbers-alpha-numeric grading system (eg. A1 for Wassce). Each country follows a specific grading system. This property is needed to differentiate between different grading systems. Grading System By Country.

Discussion
editI think the relationship should probably be expressed the other way around. For example: WASSCE (Q3308424) -> is a grading system for -> mathematics (Q395). Lectrician1 (talk) 13:59, 26 April 2022 (UTC)
- Thank you for this feedback. However, per the guidelines for adding examples to the property requests, it states to use ITEM -> value. Hence, the reason for using this format. So the example is reading: the subject mathematics (Q395) has a grading system WASSCE (Q3308424). The reason is, a particular subject may have one or several grading systems. Per the model that I am working with found here, the grading system (WASSCE) is a property of the Item (Ghana National Curriculum for Senior High School). The inverse is also possible where WASSCE (Q3308424) is the grading system for several subjects - but not for this use case. Andrews Lartey (talk) 17:58, 26 April 2022 (UTC)

- Comment Example 1 does not seem to hold entirely. Mathematics is tought in many places, and for instance in my home country the Netherlands generally scale 1-10 is used in allmost all cases. Lymantria (talk) 21:10, 24 August 2022 (UTC)
- @LymantriaThank you for the observation. The WASSCE (Q3308424) has a sample here shows the Alpha-numeric Grading system as A1 representing a total score 75% - 100%, B2 representing a total score 70% - 74%, B3, C4, C5, C6, D7, E8 and F9.
- Again, Basic Education Certificate Examination (Q15917594) has similar grading system which is just Numeric only as grade 1 represents a total score of 75% - 100%, grade 2 representing a total score 70% - 74%, 3, 4, 5, 6, 7, 8 and 9. Dnshitobu (talk) 10:42, 1 September 2022 (UTC)
- Support This would be interesting for schools that have "weird" grading systems, like the "narrative evaluation system" used at University of California, Santa Cruz (Q1047293) prior to 2000. Looking at the values used in the examples, it looks like they are are instances of rating system (Q28873665). Perhaps we should make a more specific "grading system" subclass that only applies to academic evaluations? This should be included as a value constraint when this property is created. — The Erinaceous One 🦔 04:33, 6 September 2022 (UTC)
- Comment There are some important questions that should be answered before this property is created. Namely,
- What qualities makes a grading system distinct from others? Should, for example, the values for the proposed property indicate both labels used (letters vs. numbers vs. descriptions) and the range of values used in the system ("A, B, C, ..." vs. "1, 2, 3, ...", etc.)?
- What classes of objects does this property apply to? The three I can think of are educational institution (Q2385804), course (Q600134), and test (Q27318). Should these all be modeled the same way? In the US, most schools use a numeric GPA, most classes use letter grades (based on percentages, sometimes), and most tests use percentages or letter grades. There is some overlap between each.
- At a given point in time, would each item have a unique value for the proposed property? Some colleges and classes allow students to choose between pass/fail and a letter grade.
- Should we make a distinction between grading systems that are subjective vs. objective? For example, an English paper is graded based on the opinion of the grader but a multiple choice test is not. Math exams are somewhere in the middle.
- Before this property is created, I would like to see examples of how this property would model the following grading systems:
- Letter grades with different ranges (most US colleges use F=0 and A=4, but some US high schools use a range of 0 to 5, where A=5 for advanced placement courses).
- Letter grades with and without plus/minus grading (i.e., are "A-", "A", and "A+" all possible or only an "A"?).
- Percentage (as in a test that reports 68% of answers correct).
- Percentile (as in tests that reports a student scored in the top 12%).
- Pass/Fail
- Other? Perhaps some schools or courses use non-letter grading such as "acceptable", "outstanding", etc.

- Here are some examples of how this property could be used. I will start with the Graduate Record Examinations (Q1197756) test. For the GRE test, there is both a numeric score and a percentile given and there are three different test sections which have different number ranges. Thus, I think we should simply put multiple statements on the GRE item:
- Graduate Record Examinations (Q1197756)'grading system'percentile rank (Q13200112).
- Graduate Record Examinations (Q1197756)'grading system'numeric grading system (Q113578547)
lower limit (P5447)'130' upper limit (P5448)'170' 'relative to''quantitative reasoning' - Graduate Record Examinations (Q1197756)'grading system'numeric grading system (Q113578547)
lower limit (P5447)'130' upper limit (P5448)'170' 'relative to''Verbal reasoning', - Graduate Record Examinations (Q1197756)'grading system'numeric grading system (Q113578547)
lower limit (P5447)'0' upper limit (P5448)'6' 'relative to''analytical writing'
- For a school, we could have the following
- 'Washington High School''grading system'4.0 GPA scale (Q113962345)
- 'Lincoln High School''grading system'5.0 GPA scale (Q113962579)
- 'UCSC''grading system'narrative evaluation system (Q113962270)
- For classes, we could have the following
- 'AP Physics''grading system'A, B, C, D, E, F grading system with plus/minus (Q113962476)
- 'Chemistry''grading system'Letter grading system (Q113962427)
- 'History''grading system'pass/fail grading system (Q113962154)
- I still am not sure how to handle systems that have a grading system that is both, say, A, B, C, D, E, F grading system with plus/minus (Q113962476) and 4.0 GPA scale (Q113962345). Any ideas?

- @Lectrician1:, @Dnshitobu:, @Lymantria:, @Andrews Lartey: Do you have any thoughts on my comments, above? Do the examples I give seem like a good way to use the proposed property? Are there any other examples we should consider? — The Erinaceous One 🦔 04:22, 18 September 2022 (UTC)
- This seems like a good approach. Lymantria (talk) 06:49, 18 September 2022 (UTC)
- @The-erinaceous-one So for the AP Physics class example, would you be documenting that AP Physics is a class availible at a school (idk if we have a "has class" property) and then 'grading system would be a qualifier of the AP Physics value? Lectrician1 (talk) 02:44, 19 September 2022 (UTC)
- @Lectrician1: No, I meant that example to be on an course (Q600134) item such as AP Chemistry (Q13412119)grading systemA, B, C, D, E, F grading system with plus/minus (Q113962476) (this is just an example, I haven't researched the correct value). This example is somewhat confusing because each AP topic has one or more courses associated with it and each course has a cumulative exam. A clearer example would be UNIV 100: The Student in the University (Q113990090)grading systemA, B, C, D, E, F grading system with plus/minus (Q113962476) because this refers to a specic course at a specific shool with a specific grading policy. Generally, we don't want to input every class from every school into Wikidata, but there might be some noteworthy classes that are worth including. In general, I expect that the the proposed property will be used most often for schools and standarized tests.

- @The-erinaceous-one I don't think AP courses have a specific grading system. Usually that is up to the school to implement and can thus vary from school to school. Lectrician1 (talk) 12:48, 19 September 2022 (UTC)
- @Lectrician1: Yes, you're right, that made it a poor choice of example. I expect that the proposed property will rarely be used on classes, so I think it would be better to focus on schools and stardized tests. (On a related note, I started a discussion in the WikiProject Education regarding the organization of AP classes in WikiData.)

- To model schools that, say, use an 4.0 GPA scale (Q113962345) and a A, B, C, D, E, F grading system with plus/minus (Q113962476), should we simply have a separate 'grading system' statement for each? For example,
- 'Washington High Schoolgrading system4.0 GPA scale (Q113962345)
- 'Washington High Schoolgrading systemA, B, C, D, E, F grading system with plus/minus (Q113962476)
- Or, should we find a way to combine these two pieces of information? Or should we only include one of them with the proposed property? — The Erinaceous One 🦔 07:51, 21 September 2022 (UTC)
- @Lectrician1 & @The Erinaceous One Thank you so much for your detailed comments, with examples. The team has been meeting the advisory council for this project who have shareed their insights as well. At the moment, we are on the drawing table to better align this particular propery with all the tangents you have pointed out.
