**
What is an average score on the GFTA-3? ›
**
The GFTA-3 provides standardized scores with a **mean score of 100**, and a standard deviation of 15. Standard scores between 85 and 115 are considered to be within the typical range.

**
How to score intelligibility on GFTA-3? ›
**
During administration of the Sounds-in-Sentences test, the examiner listens to each sentence the individual repeats and rates the individual's intelligibility for that sentence as **1 (good), 2 (fair), 3 (poor), or 4 (no response)**.

**
What age is the GFTA-3 for? ›
**
The GFTA-3 is an individually administered standardized assessment used to measure speech sound abilities in the area of articulation in children, adolescents, and young adults ages **2 years 0 months through 21 years 11 months**.

**
What is the formula for calculating raw score? ›
**
Raw scores represent the actual numerical score that a person achieves on a test or examination. The formula for calculating a raw score is **X = (Z * SD) + Mean**, where X is the raw score, Z is the z-score, SD is the standard deviation, and Mean is the average score of all people who took the test.

**
How long does the GFTA 3 take to administer? ›
**
Assess multiple occurrences of high frequency phonemes in the same amount of time (**under 15 minutes**). Quickly and easily administer and score.

**
What does a standard score of 77 mean? ›
**
As a rule of thumb, on a scale where 100 is the average (like the CELF-5): a standard score of 70, or less than 70, suggests a severe impairment; a standard score of 71-77 suggests a **moderate impairment**; a standard score of 78-85 suggests a mild impairment; and.

**
How intelligible should a four year old be? ›
**
Between 4 years and 5 years, children should be **75-90% intelligible to an unfamiliar listener without context**. And beyond 5 years old, children should be 90-100% intelligible to an unfamiliar listener without context.

**
What does a standard score of 79 mean? ›
**
Assuming a normal distribution, a standard score of 79 is **1.5 standard deviations below the mean**, based on the commonly used scale with a mean of 100 and standard deviation of 15.

**
Does the GFTA assess phonological processes? ›
**
The Goldman-Fristoe Test of Articulation—Third Edition (GFTATM-3), now in English and Spanish, and Khan-Lewis Phonological Analysis—Third Edition (KLPATM-3) offer comprehensive articulation and phonology assessment.

"His intelligibility was rated a "5" (speech is difficult to understand with many words unintelligible on a 7 point rating scale where "1" = no noticeable differences from normal, **"7" = unintelligible**).

**
How do you score intelligibility? ›
**
**The scale is:**

- completely intelligible in conversation.
- mostly intelligible in conversation.
- somewhat intelligible in conversation.
- mostly unintelligible in conversation.
- completely unintelligible in conversation.

**
What is the normal range for the GFTA 3? ›
**
**85 to 115**: Within the normal range (100= average)

**
How to score GFTA sounds in words? ›
**
The Sounds-in-Words test is used to evaluate an individual's articulation skill when labeling single words. The examiner presents a picture stimuli for the individual to label. **The examiner scores each consonant and consonant cluster sound in the word as a correct or incorrect production**.

**
What is the difference between GFTA and DEAP? ›
**
**Nearly half of the GFTA-2 is composed of multisyllabic words whereas the percent of multisyllabic words on the DEAP is fewer in number**. Instead, the DEAP is mostly composed of words following a consonant-vowel-consonant pattern.

**
How do you calculate raw grade? ›
**
Add up all the total score for each component. Convert the sum for each component to percentage score. Divide the total raw score by the highest possible score, then multiply the quotient by 100%. Convert the percentage scores to weighted scores.

**
How do you calculate raw z-score? ›
**
The formula for calculating a z-score is **z = (x-μ)/σ**, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.

**
How do you calculate raw score to scaled score? ›
**
Each correctly scored item below 50 is calculated by **taking the number of correct answers, multiplied by the scaled-score value (~3), and added to 100**; a raw score of 20 would be approximately a scaled score of 160 (20 x 3, + 100), whereas a raw score of 40 would be approximately a scaled score of 220 (40 x 3, + 100).

**
What is a raw test score? ›
**
A raw score is **a single score that is derived from a test or an observation**. Cumulative percentages determine placement among a group of scores. Raw scores are also known as X values and are usually not useful by themselves. Converting raw scores into cumulative percentages allows for meaningful comparisons.
