H2, E2, ERK1 Children's Writing was developed by the Cooperative State University Baden-Württemberg, University of Education. It consists of approximately 2,000 texts written over four months by 173 German school children age six through eleven years.

The data in this corpus was collected by elementary schools in Baden Württemberg, Germany and digitized at the Cooperative State University during the 2016/2017 school year. Three second, third, and fourth grade classrooms participated in the collection.

Texts were written within regular class settings. The students were presented with a picture and were asked to write a story, to describe the picture or if unable to write a text, to list what they saw in the picture. The pictures were designed to enhance the output with respect to important spelling error categories, namely, the marking of short vowels with a silent consonant letter and the correct spelling of the long vowel <ie>. The children were allowed at least 15 minutes to write the texts. This exercise was repeated weekly for nine or sixteen weeks depending on the program.

LDC has also released H1 Children's Writing (LDC2016T01).


There were 173 total participants. 100 students were multilingual, and further metadata is available for 166 of the 173 children. The following is included for each text in the database: school week of collection; school type; age; gender; grade/classroom; language spoken at home; and school materials used.

In all, 2,117 texts representing 118,621 tokens were collected. The texts were digitized in two forms: (1) the original text, including all errors (achieved), and (2) the intended (target) text, where all spelling errors were removed. Annotations were added to both the achieved text and the target text to distinguish words that should not be analyzed for spelling errors, such as names or foreign words. For sentence-level analysis, syntax errors were annotated by marking substitutions, deletions and insertions at the word level. In such cases, the used word was analyzed for spelling, and the correct word was used for sentence structure analysis.

Original handwriting is presented as pdf documents and the converted text as UTF-8 plain text in csv documents.
