Document 2: A Measuring Scale for Ability in Spelling, Leonard P. Ayres (1915)

Read the research base for development of the Ayres List, one of the high frequency spelling word lists used in JCSpell lessons (JCSpell Lesson Planner series and JCSpell Word Analyses series).

JCSpell has incorporated the Ayres List not only because it is a list of high frequency words for both writing and reading, but also because it is a list of words ranked by spelling difficulty. Students are always moving upward in spelling difficulty as they systematically and explicitly analyze words during the "Think to Spell" lesson routine.
