DSS

DSS Score = # of points / # of utterances

Jay's Developmental Sentence Score on the 25 utterances sample is 100 points divided by 15 sentences = 6.67. One limitation of this analysis is that the DSS uses a 50 utterances sample. Only children that score below the 10 percentile or more than one standard deviation below the mean are likely to need intervention. Jay scores at the 50th percentile, which shows a benchmark score of 6.64 for 3 years 6-month.

Correct/Incorrect Form Analysis

Jay's speech sample notably lacks use of past tense, third person, possessives, contractible copula, and contractible auxiliary phrases. Referencing Brown's morphemes, Jay's use of language corresponds with the age of mastery range for 28 to 46 months. At 41 months of age, Jay is approaching the upper end of the range but his expressive language appears to be developing normally. It is possible that the language sample has not produced many opportunities for Jay to use past tense, as it appears that he is narrating his play -- perhaps interacting with objects while an adult looks on.

Type Token Ratio

Jay's Type Token Ratio (TTR) scored the conventional way is .67. This score is calculated by dividing the number of different words produced in the sample by the total number of words in the sample. In Jay's case, this calculation is TTR = 52 / 78 = .67

When using the Stickler (1987) method of calculating the Type Token Ratio (TTR), the calculation is as follows: The number of different words divided by the total number of words equals the TTR percentage. For Jay's sample, the TTR using the Stickler method is: 47 different words / 69 total number of words = .68 TTR. This ratio is within the expected range for normally developing children.

Summary Report

Jay is a 3-year 5-month-old boy who has been enrolled in an Early Childhood Education classroom for the past half-year of school. Jay's birth history is unremarkable, and he has achieved gross and fine motor developmental milestones at appropriate ages. He is making progress with articulation: Jay exhibits several consonant clusters, and his / r / sound is still affected by gliding. Jay's receptive language appears to have developed at appropriate levels. However, Jay was… READ MORE
