15Measuring Progress and Steering Therapy

TThe daily check: the Ling six-sound test

The Ling sounds sample speech energy across the frequency range, so a quick daily check that a child detects (and, when older, identifies) all of them confirms the device is delivering audible sound from low to high frequencies before any therapy begins. A poor or changed Ling response is an early warning that something is wrong with the device, the program or the ear, prompting a check of charge, processor function and recent changes before assuming the child has regressed. Because younger and less experienced listeners are the least able to report a problem, their equipment and listening checks must be done more frequently, ideally as part of the daily school and home routine. The test is deliberately simple and free, which is why it is the workhorse of the home and classroom; staff and parents can be trained to run it without specialist equipment. Ling is a screen, not a diagnosis: it tells you that access to sound is or is not present today, which is the precondition for every other rehabilitation activity to be worthwhile.[2009][2020]

TTracking real-world listening: parent and teacher questionnaires

The Meaningful Auditory Integration Scale (MAIS) uses a structured parent interview of 10 questions probing a hierarchy from attachment to the device and simple detection through to recognition and comprehension of speech, each scored 0 to 4 by how often the behaviour occurs. The Infant-Toddler MAIS (IT-MAIS) adapts this for very young children, sharing many MAIS items but adding questions on an infant's vocal behaviour, and is typically used with parents of children roughly 1 to 3 years old. The LittlEARS Auditory Questionnaire charts early auditory development against a normative curve built from normal-hearing infants and has been validated in cochlear-implanted infants and toddlers, where scores rise with duration of hearing experience. The Meaningful Use of Speech Scale (MUSS) is the spoken-output counterpart, tracking how the child uses speech to communicate, so listening and talking are monitored in parallel. These tools capture behaviour in everyday life that the booth cannot see, and serial administration turns single scores into a trajectory that shows whether the child is gaining as expected. Early intervention is rewarded: in serial data, the youngest-implanted children gain fastest, with many matching normal-hearing peers' scores within months, while later-implanted children gain more slowly and less predictably.[2009][2017][2016]

TGlobal outcome ladders: CAP and SIR

The Categories of Auditory Performance (CAP) scale rates everyday listening on a hierarchical ladder from no awareness of environmental sound up to using the telephone with a familiar talker, and is simple enough for parents and non-specialist staff to apply. CAP has demonstrated good inter-user reliability, which is why a non-specialist's rating can be trusted to track change over time rather than reflecting who happened to score it. The Speech Intelligibility Rating (SIR) is the speech-output companion, classifying a child's spontaneous connected speech into five hierarchical categories from prerecognisable words up to speech intelligible to all listeners. Used serially, CAP and SIR give a clinic a low-cost shared language for progress that travels well across teams and settings, complementing rather than replacing detailed booth testing. Because they are global ladders, a child can sit at the same category for a while as skills consolidate; the concern is failure to climb over an appropriate interval, not slow movement within a step.[1998][2009][2011]

CReviewing goals and responding to a stall

Functional measures feed goal review: when a child is climbing the questionnaires and ladders as expected, therapy continues and targets advance; when progress flattens, the tools have done their job by flagging it early. A genuine stall triggers a structured workup rather than more drilling: confirm device function and listening access (start with the Ling check), revisit the program/MAP, and exclude a new middle-ear or medical problem. If the device and program are sound, the stall links back to the poor-performer evaluation in programming and to the outcome science chapter, where factors such as duration of deafness, cochlear and neural status, and additional disabilities are considered. Over-drilling is itself a risk: cultivating isolated listening skills can push auditory scores ahead of the child's wider language and play, so a plateau in one tool must be read against the whole developmental picture. The family's longitudinal view and the teacher of the deaf's classroom observations are part of the data, ensuring that progress is judged across real settings and not only on the day of a clinic visit.[2009][2020][2011]
