Week 2.2 Standardized Testing Flashcards
what may standardized testing be used for
determine eligibility (discriminative or norm-referenced) measure progress (evaluative or criterion referenced)
what are norm-referenced tests
determine eligibility
standardized on groups of normal children
compares child to others
provides a snapshot
can you use norm-referenced tests to track change over time
no, and you shouldn’t use it for program planning
what is criterion referenced
measure progress, evaluates the individual performance in relation to a field standard.
what does the criterion referenced compares children to
compares the child to himself
can you use criterion referenced to plan a program, or track change
yes.
what does reliability test for
results are repeatable
what does validity show us
tests what we want it to test
what is the difference between sensitivity and specificity
sensitivity: minimizes false (-),
specificity: minimizes false (+)
what is the raw score
the percent they got correct
what is the age equivalence
mean age when 50% of children would have tested similarly
developmental quotient
ratio between Childs actual score and Childs age (think IQ scores)
what is the standard scores
z and t scores, expressed in terms of standard deviations
percentile
norm referenced, the 50% is average
what is percentage
the number of items they got correct
give an example of percentiles
15th percentile, their skills are 15% or more better than the other kids
at what percentile are we concerned
below the 5th or 10th percentile
give an example of percentile and percentage in same example
if 80% is the highest score in the class, then they got an 80 percent, but are in the 99th percentile.
what 3 tests are norm referenced
AIMS, Bayley III, PDMS-2
that are the criterion test
INFANIB, GMFM
what age does the INFANIB test
1-18 months
what age for AIMS
birth to 18 months
what age for BAYLEY-III
1-42 months
what age for PDMS-2
1-72 months
