“Sixty words per minute for all”: Why this goal for the early grades?

Short paper arguing that failure to learn reading is the primary reason for repetition in the early grades. Students cannot learn from books until they can read fluently, and they may even be unable to solve verbal problems written in maths books. Abadzi argues that by by the end of grade 1 students should be able to read very common words, albeit haltingly. By the end of grade 2 at the latest, students should be reading simple texts fluently, at a rate of at least 60 words per minute.
