The NAPLearn grading algorithms were originally developed at an Australian university by a team of PHD students. These algorithms have been licensed by Rembiont and subsequently enhanced for use in NAPLearn.
NAPLearn uses proprietary Natural Language Processing techniques to grade your essays. Within the system, NAPLearn can detect events in an essay to help understand what a student is writing about. We then use this information to assign scores for the various criteria.
NAPLearn is designed to be used as an essay practice site and estimated grades are intended as a guide only. Due to many factors, different results may be obtained in actual test conditions.
Although the scores provided by NAPLearn may not be the same as the scores that the essay will be awarded from an actual NAPLAN test, in most cases they will be similar. On various tests involving hundreds of essays the Rembiont Grading Engine had a correlation of around 80% with human markers, which is similar to the correlation between different human markers grading the same essays.
The highest variances in scores are found at the lowest decile and the highest decile of the score ranges. For instance, our technology is limited in recognising clever use of rhetorical devices which would be clearly apparent to a human grader. Instead, we make use of "proxies" to help determine scores. Proxies are metrics which tend to correlate with the quality of the essay.
In summary, we do not claim that NAPLearn grades as well as a teacher would do. However NAPLearn will return indicative grades very quickly, in seconds rather than the hours or days involved when a teacher grades your work.
NAPLearn analyses essays using the following criteria:
Audience - The writer's capacity to orient, engage and affect the reader
Ideas - The creation, selection and crafting of ideas for a narrative
Cohesion - The control of multiple threads and relationships over the whole text, achieved through the use of referring words, substitutions, word associations and text connectives
Character and setting - Character: The portrayal and development of character, Setting: The development of a sense of place, time and atmosphere
Sentence structure - The production of grammatically correct, structurally sound and meaningful sentences
Paragraphing - The segmenting of text into paragraphs that assists the reader to negotiate the narrative
Spelling - The accuracy of spelling and the difficulty of the words used
Grading Engine Improvements July 2021
We have made improvements to our grading engine to improve grading accuracy. Over the past few weeks we have refined various aspects of our grading algorithms and subsequently verified our automated scoring results against human scored essays in order to further improve human to automated score correlation. As a result, you may notice differences in scoring outcomes. If you graded an essay prior to 26 July and re-grade the same essay you may receive a slightly different score.
Grading Engine Improvements October 2022
We have made improvements to our grammar and spelling checks. We now identify significantly more styles of grammatical errors and our dictionaries have been updated with many recently introduced words in common usage (e.g. Covid, Tiktok). As a result, you may notice differences in scoring outcomes. If you graded an essay prior to 16th October and re-grade the same essay you may receive a slightly different score.
