Methods, systems and interfaces are used in the teaching, practicing, and testing of spelling skills with a computer system. An instructor is provided words, groups of words, and filters for creating word lists to administer to one or more students in a preview. Previews are administered to each of the students for generating individualized word lists that are used to administer practice exercises and practice tests. The individualized word lists can also be used to administer final tests to the students. Some interfaces are used for tracking words passed off by the students as well as words the students fail during the final testing. Graphical user interfaces are provided for instructors and students. Some of the instructor interfaces allow instructors to manage students and student groups and to administer previews, word lists, practice exercises and practice tests, final tests, and reporting.
