- temporal test
- auditory attention test
- binaural integration-ability to repeat everything that is heard
-

- aud decoding-difficulty filling in missing pieces have the dime v have you got a dime
- integration-difficulty connecting the linguistic content with the prosodic intent (tone of voice)
- temporal/prosodic-difficulty understanding the intent rather that the content

- depends on the CAPD
- preferential seating
- in classroom accommodations
- assistive listening devices
- games
- computer programs

- normal hearing

- speech/lang evals
