In case you missed it, the GED is changing -- dramatically. It has been purchased by Pearson and the new test will be more difficult and much more expensive. Here's a news article that sums up the basics: (Times-Daily article).
The following message from the SDE provides some information that your students might need:
The current version of the GED® Test will expire at the end of 2013. The 2002 Series GED® test will be replaced with the new 2014 GED® test on January 2, 2014.
Those who have taken the 2002 Series GED® test, but not passed all five parts, have until the end of 2013 to pass the complete series and receive their high school credential. If this does not happen by the end of 2013, test-takers will lose any passing scores and will have to start over with the new 2014 GED test series in order to receive their high school credential. In addition, paper-based testing will no longer be available in 2014. Test delivery for the new 2014 GED® test will only be available through computer-based testing.
GED preparation classes are available statewide through local Adult Education Programs. Click here for a listing of the Oklahoma GED Testing Center or Adult Education Program nearest you.
