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• Strategies
Follow-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
