Remediation Program• Home-based auditory training packages with

audiologist support during program – SPD - LiSN & Learn, – Memory Deficit - Memory Booster

• FM system for DDT fail or difficulties in noise• StrategiesFollow-Up• Review COSI-C• Teacher version of Listening Inventory For Education

(LIFE - Anderson and Smaldino.)• Repeat relevant test from battery.

Other considerations• Main reasons for incomplete auditory

training– Ongoing at time of data collection

• L&L = 11%; MB = 10%– Lost contact with families despite numerous attempts

• L&L = 25%; MB = 52%– Unknown/data unavailable

• L&L = 43%; MB = 24%• Difficulties getting LIFE returned from

teachers• Setting & evaluating S.M.A.R.T. goals

Conclusions• 61.3 % of children referred were diagnosed with one of

the target auditory processing disorders.• Both auditory training programs led to significantly

improved test scores (LiSN-S and NMR both WNL)– The majority of children showed significant

improvements in real life settings• FM fittings yielded improvements in real-life

performance.• Goal setting, evaluation and teacher

questionnaires are vital for evaluating success– Family support essential throughout program– Additional strategies needed to engage teachers in

evaluation
