ACE behaviors (attention comprehension and Effort)
- all assessments assume the children being assessed they are fully attending the task at hand
- understand exactly what they are expected to do.
- give full effort
administration behaviors
-define how an assessment should be administered and scored.
alternate form
- methods for testing reliability
- 2 equivilant forms of test are created
- children split in half and administered the tests
- divide two groups
Split half
- other method of testing
- single test is administered to one group of children then divided into 2 forms.
concurrent validity
-statistically measures the relationship between an existing instrument with established validity and a new instrument that assesses the same attribute.
construct validity
- concerned with demonstrating that what an assessment item measures is representative of a construct.
- ex; sportsmanship, anxiety, and coordination
Criterion (predictive) Validity
examines the degree to which one or more test scores can be used to predict performance on a future related event.
Content Validity
concerns collecting evidence to support that what is measured by the instrument reflects what the instrument is designed to measure.
Face (Logical) Validity
- simplest and most subjective source of validity
- evidence to support an assessment instrument.
- needs to be a direct connection.
validity
- function of what is measured by the test
- how the test results are used.
Reliability
instrument refers to the consistency of the result obtained over multiple administrations.
Norms
-there to help teachers interpret how their students are performing compared with other students, who have taken same assessment.
Objectivity
- special reliability
- focuses on the consistency of the results obtained by the same assessor across multiple administrations.
intra-class correlation
is that is uses all the data that have been collected and allows for the variance to be examined from three sources.
1-students.
2-trials
3-interaction of students by trials
Pearson product-moment
- test reliability
- uses all the data
- ??
Scoring precision
- a function of what us measured and the amount of skill needed to make the measurements.
Student performance variability
??
Test-retest reliability
- simplest way to test reliability
- an instrument is administered twice to the same group of children and Ben a correlation, or degree of movement between results is calculated
Intra and inter reliability

Tra one tester
Ter multiple testers
PURPOSE OF CONDUCTING ANY ASSESSMENT
MAKE INFORMED DECISIONS AND TO COLLECT ACCURATE DATA. AND MORE
TYPES OF VALIDITY
- FACE
- CONTENT
- CONCURRENT
- CONSTRUCT
- CRITERION
THREE MAJOR FACTORS THAT EFFECT RELIABILITY OF ASSESSMENT:
- ADMINISTRATION PROCEDURES
- SCORING PRECISION
- STUDENT PERFORMANCE VARIABILITY.
