Hi Darlene,
If you are referring to word divisions in the literary lessons, no word divisions are required after lesson 12.
If you are referring to the Manuscript, no word divisions are required, however if you do choose to divide a word and it's divided incorrectly, it will be marked as an error.
If you are referring to an actual project that you are working on, then it becomes an agencies decision.
Keep in mind that even though word divisions may not be required for lessons or the Manuscript, hyphenated compound words and expressions should still be divided at the hyphen.
See page 12-4 in the 2009 Literary Lesson Manual
Thank you for the question.
