How do you read Celf results?

As a rule of thumb, on a scale where 100 is the average (like the CELF-4): a standard score of 70 or below suggests a severe impairment warranting urgent treatment; a standard score of 70-77 suggests a moderate impairment; a standard score of 78-85 suggests a mild impairment; and.

What is a normal standard score?

It is also known as a standard score, because it allows comparison of scores on different kinds of variables by standardizing the distribution. A standard normal distribution (SND) is a normally shaped distribution with a mean of 0 and a standard deviation (SD) of 1 (see Fig. 1).

What does a standard score of 130 mean?

Standard scores have a larger range of below 69 to above 130, with an average score of 100 points. Scores that fall more than 15 points below or above the average score of 100 (more than one standard deviation below or above average) represent performances that are further below or above average.

What does a celf-4/celf-p2 score of 90% mean?

This is a very low score and indicates that he is significantly delayed compared to his peers.

What is the average and standard deviation of the celf-4?

Once the scaled scores of each subtest is added, you get another number. This number on the CELF-4 is also then scaled. This becomes the Language Index. Here, the average is 100, and the standard deviation is 15.

What is a “normal” language index on the celf-4?

This number on the CELF-4 is also then scaled. This becomes the Language Index. Here, the average is 100, and the standard deviation is 15. So the “normal” range is 86-114. Again, you want to be within the average range. Standard Deviation: The standard deviations can also refer to other scores and rankings.
