Users transitioning from the Batería III® to the Batería IV® may have noticed that the composition of the tests within the batteries changed:

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:
