This study investigates the type of errors made by middle school heritage learners in written German. The errors are classified into four categories: consonant errors, capitalization errors, vowel errors, and deletions. The study finds that compared to previous research regarding German first-grader spelling, these middle school students produce significantly more errors when writing in German. There are four participants, three female and one male, ranging in age from 10-14, all of whom are enrolled in a Saturday school enrichment class and have been identified as heritage learners prior to class placement. The results indicate a need for more intensive and targeted spelling instruction and a portion of the paper is dedicated to teaching implications. / text
