The New Century Version of the Bible is a revision of the International Children's Bible. The ICB was aimed at young readers and those with low reading skills/limited vocabulary in English. It is written at a 3rd grade level (from the introduction) and is both conservative and evangelical in tone. The New Testament was first published in 1978 and the Old Testament followed in 1986. The ICB was revised somewhat to be a bit more sophisticated (reading level grade 5) and was dubbed the New Century Version, released in 1987. A gender-neutral edition was first published in 1991, supplanting the original.
