Prevalence of Speech Sound Disorders (
• 7.5% of children between 3 and 11 years have significant system sound disorders needing treatment, 2.5% of those children still have major substitution and deletion past 4 years.

What is the first step of Hudson phonological acquisition?
1 yearCanonical babbling and vocables
What is the second step of Hudson phonological acquisition?
1 1/2 years Recognizable words; CV structures; stops, nasals, glides
What is the third step of Hudson phonological acquisition?
2 years Final consonants, communication with words “syllableness”
What is the fourth step of Hudson phonological acquisition?
3 years/s/ clusters, anterior-posterior contrast, expansion of phonemic repertoire
What is the fifth step of Hudson phonological acquisition?
4 years Omissions rare, “most simplifications” suppressed, “adult-like” speech
What is the sixth step of Hudson phonological acquisition?
5-6 yearsLiquids /l/ @ 5 years /r/ @ 6 yearsphonemic inventory stabilized
What is the seventh step of Hudson phonological acquisition?
7 yearsSibilants and “th” perfected, “adult standard” speech
Critical Age Hypothesis:
children need to be intelligible by 5½ years of age or they are likely to have difficulty with decoding and spelling -
“Matthew Effects”:
Stanovich compared achievement levels of children who are poor beginning readers with their peers who have good decoding skills and noted that the gap widens over timeEarly intervention is important because children with disordered phonological systems are risk for decoding text, comprehension, spelling, writing, and word finding.
• Purpose of Assessment
Identify specific communication skills• Guide intervention design• Monitor growth and progress• Qualify a person for special services
Application of comprehensive communicative assessment
• Identify the presence and absence of a disorder• Identify goals and strategies to meet• Monitor progress toward therapy outcome
What is a norm-referenced test?
o Answers→how does a client compare to average?o Standardized→ reliable from person to person, from tester to testero Helps focus and sharpen observational skills & decide if a problem exist (reliability & validity)
What is a criterion-referenced test?
o Answers→ how does the client compares to an expected level of performanceo Can be standardized or not standardizedo Identifies one’s performance according to predefined criteria
Performance-based measures
Describe an individual’s skills or behaviors within the actual context of useWhole word accuracy %Identifiable word accuracy %
Dynamic assessment
Identifies the amount and type of support needed to determine a client’s range of performance uses a “test-teach-retest” forma tVygotsky’s “Zone of Proximal Development.”
• Percentile Ranks (PR)
state the percent of persons in the norming sample who scored the same as or lower than the student.>99,95, 84, 75, 50, 25, 16, 5 >1
Standard Scores (SS)
have an average (mean) of 100 and a standard deviation of 15. The middle half of these standard scores falls between 90 and 110. Average range is between 85 and 115145, 125, 115, 110, 100, 90, 85, 75, 55
Scaled Scores

PRIMARY TARGET PATTERNS
-Word Structures [OMITTED Segments]-/s/ Clusters [For OMISSIONS, but NOT for Distortions (e.g., Lisps)]-Anterior/Posterior Contrasts [after stimulability evidenced]-Liquids (even if not Stimulable)
Word Structures [OMITTED Segments]
Syllableness Vowel sequences in compound words 2-syllables; 3-syllablesCV Word initial p,b,m if lackingVC Voiceless final stops p,t,k; final m,n if lackingVCV e.g. apple
/s/ Clusters [For OMISSIONS, but NOT for Distortions (e.g., Lisps)]
Word-Initial /sp/,/st/,/sm/ (incorporate “it’s a ____” [/s/ cluster word]Word-Final /ts/,/ps/,/ks/ (enhances awareness of plurals)
Anterior/Posterior Contrasts [after stimulability evidenced]
Velars (if “fronter”) Final /k/, then initial /k/,/g/ (occasionally /h/)Anterior (if “backer”) Alveolar stops: final /t/, initial /t/ & /d/(possibly /n/)
