Batería III COG vs. Batería IV COG

Batería III ACH vs. Batería IV ACH


As you can see, when transitioning from the Batería III ACH to the Batería IV ACH, there are specific Oral Language tests (Picture Vocabulary and Oral Comprehension) that were removed. 


The Spanish versions of these tests can be found in the WJ IV Oral Language Battery, specifically, Tests 10 and 11. There is also a Spanish version of the Understanding Directions test available for use on the WJ IV OL Battery:
