norm-referenced tests (standardized)
criterion referenced tests
Advantages of Authentic Assessment Approach
-more natural/in real world setting
-allows for clients self-monitoring/coaching
-allows for individualizations
-flexibility (divert from standardized testing procedures)
Disadvantages of Authentic Assessment Approach
-lacks natural environment functioning and objectivity
-lacks validity/reliability since its not standardized
-requires more experience
most important part of a standardized test; explains how to administer test, who can administer it, the scoring instructions and interpretation guidance
Code of Fair Testing Practices in Education
choose good test for each client
represented in normative sample
represents clients abilities/disabilities
Code of Ethics for SLPs
doing what is right and good
the way we asses and then identify the way someone stands out from others
sometime result of an evaluation
can be dynamic and ever-changing
Can SLP-As come up with a diagnosis?
dynamic, on going process but often precedes the diagnosis
assist in determining severity of a problem and qualifying kids for services
What is the first step in intervention planning?
Which two words can be used interchangably?
evaluation and assessment
idea of how a client compares to people his/her age
group of alike individuals
part of the population being tested
take random representatives from the population to form the sample
ex. all of the 2nd graders from 3 schools instead of takin random kids from different classes
Does the sample size matter?
Yes b/c if not enough people are included in normative sample then we wonder if they sampled enough people to represent the population
what we use to compare our clients to; provide us with scoring information
What should normative data include?
other factors such as hearing status, disabilities prior to testing (ex. down syndrome)
Norm Referenced Test
may be called formal/standardized
includes a normative group
What is norm referenced test data analyzed to determine?
mean, standard deviation, etc.
What are the pros of a norm referenced test?
-used to compare to a group
-needed for placement
-can be used to compare different areas (vocab vs. syntax)
-qualifies/disqualifies clients for services
What are the cons of a norm referenced test?
-destroys the social-interactive quality of language
uses a performance standard or a set of expectations
ex. pragmatics checklist
emphasizes individual performance rather than comparing similarities to a groups performance
sometimes test for a sequential skill or outcome measure (how many times they demonstrate a particular behavior)
judge against set of expectations
when someone takes a test, he/she earns a score which can be interrupted in the context of other scores. mean, median and mode all describe the average of the score frequency distribution
What is the easiest way to qualify someone for insurance or funded services?
standardized test scores
the arithmetic average; most common measure
a counting average. the midpoint in a set of scores
most frequent or popular score in a set and it occurs most frequently in distribution
When do we find the statistic analyzes information?
the test manual
aka dispersion; the extent to which scores differ from one another or are dispersed around the mean
they can vary but also give similar composite scores
What are the two measures of varibality?
range and standard deviation
simple calculation of difference between highest and lowest scores in a distribution
the most useful measure of variability; an average of the degree to which a set of scores deviate from the mean
tells us how scores can be interpreted on a high and low end and whether or not that score is close enough to the average to be considered average
How much a client score to qualify for services through the school system or be clinically significant?
-1.5 to 2.0 SD below the mean
What is the mean and SD for composite scores?
What is the mean and SD for subtest scores?
What is the mean and SD for z-scores?
What is the mean and SD for t-scores?
How do you find 1 SD below the mean?
subtract the SD from the mean once
If a composite score is 1 SD below the mean what would it be?
What would 2 SD below the mean for composite scores be and would this qualify for service?
What is the average for a score?
between 85 and 115
What would 1 SD below the mean for a subtest score be?
pictured representation of scores; there is a normal tendency for most scores on a test to fall around an average value; some scattered high (right side) and some low (left side)
where we plot the scores
the curve is the highest at the center b/c that is the average score achieved and the height represents the number of persons achieving that score
the few subjects scoring at the high and low ends of the normal curve
average range; 1 SD above and below the mean
scores that are falling at or below -1.5 to -2.0 SD from the mean
To qualify for services in the state of Louisiana:
-1.5 to -2.0 SD below the mean
What is a composite score that may qualify a client for services and need intervention?
rule that governs how percentile ranks are distributed among the normal curve
_______ of all scores fall within 1 SD above and 1 SD below the mean.
68% (34% on each side)
_______ of all scores fall within 2 SD above and 2 SD below the mean.
95% (47.5% on each side)
_______ of all scores fall within 3 SD above and 3 SD below the mean.
99.7% (49.85% on each side)
What do SLPs report on?
report on standard scores and percentile ranks and understand how they correlate
the actual # you arrive at when grading a clients test. many times it is the # correct but not always
What tells you how to score the test?
Raw scores are ___________.
meaningless until you convert them to a standard score
a score which indicates the number of SD units a raw score is above or below the mean
What are the three types of standard scores?
z scores, t scores, statine
9 bands of normalized standard scores; divide a score distribution into 9 parts
the point in a distribution below which a given percentage of the scores are found
What performance is a cause of clinical concern?
below the 10th percentile
Age and Grade Equivalency
least useful and most dangerous scores for test score interpretation
Standard Error of Measurement
range in scores to increase precision in determining whether the observed score of a subject is close to his/her possible true score
helps us to qualify someone/show weakness even if SS is too high in average area or disqualify someone from speech
provides a range of scores rather than an exact score for determining cutoffs for abnormality
Can screenings be completed for every disorder?
Who is confidence interval chosen by?
the clinician (how confident they are that their performance on test is represented by their ability)
identifies people with the disorder
normal but fail a test
have a disorder and pass the test
normal and pass the test
