Not everyone agrees about the minimum grade level of every translation or the formulas used to calculate them. But we offer as general guidelines the following range of USA school grade levels (taken from information provided by the publishers of the various translations wherever possible) and age levels. The first number is the grade level for which the Bible is generally considered accessible; the number in parentheses is an estimated age at which a reader can fully read and understand it:
