Assessment, Occ Analysis, Service implementation Flashcards
Normal Distribution
Bell Curve- a group of frequency distributions that have the same symmetrical shape with data points more centrally located than in the tails (ends).
Measures of Central Tendancy
a method of describing typical, average or common test scores (values) in a distribution such as Mean, Median, Mode.
Mean
the sum of a set of scores divided by the total number of scores
Median
The middle value dividing a set of scores, arranged in order of magnitude into 2 equal halves. This score at the middle with half the scores above and half the scores below. (with no single score in the middle- the 2 middle scores are divided by 2)
Mode
The score that occurs most frequently in a distribution
Standard Deviation
for a particular distribution of scores, the SD measures the amount of variability around the mean of the scores.
Standarized test
An instrument that is administered, scored and interpreted in a predetermined manner. Common types include intelligence, aptitude, achievement, interest, and personality.
Variation
A measure of a distributions dispersion, it is the square of a scores standard deviation.
Percentiles
the 99 values that divide a frequency distribution into 100 groups with 1% of the scores in each group.
Z scores
The number of standard deviation units of a given score above or below the mean
T scores
z-scores that have been multiplied by 10 (to remove the decimals) with 50 added to it (to remove the minus values).
3 levels of Vocational Assessment
Level 1: Screening
Level 2: Clinical or Exploratory
Level 3:Vocational Evaluation
Level 1 vocational assessment
Screening: conducted by VRC to determine eligibility and to find out if provision of further services is warranted. Primarily self report, medical records and limited psychometric testing like computerized interest assessments occur at this level.
Level 2 vocational assessment
Clinical or Exploratory assessment: conducted by VRC. Focus is on getting more in depth info. Could include vocational assessment and vocational counseling, detailed case study, transferable skills analysis, AT assessment, Environmental analysis.
Level 3 Vocational assessment

Achievement Tests of minimum competency
CRC exam, Drivers tests, measure basic skills and set a minimum standard for certifications or licensing
Achievement Speed and Power tests
can be designed to be “speeded” in which there are more questions that most people can answer within the alloted time or “powered” which most people can finish within the time limit.
General Achievement Batteries
Provide a profile of scores based on testing a variety of specific areas which typically include reading, language, math, science and miscellaneous.
Commonly used Achievement tests
Wide Range Ach. test 4th ed (WRAT IV)- commonly used in groups, measures word recognition, spelling and arithmetic. ages 5-94
Peabody Individual Ach- Revised (PIAT-R) for ages 5-22
Woodcock-Johnson Psycho Educational Battery- Primarily used with people w learning disabilities 2-90+
Test of Adult Basic Education (TABE)- measures adults basic education, used frequently in vocational groups
Tests of General Educational Development (GED) high school equivalency exam. typically given in educational settings, measures writing, social studies, science reading and math.
Aptitude tests
designed to predict and individuals future performance. They measure characteristics associated with the ability to acquire knowledge or skills. Used to obtain counseling information and assist client in decision making.
General Aptitude Test Battery (gat-B)
one of the most widely used by rehab counselors. Created by DOL aptitudes measured include: G- general learning ability V- verbal ability N- numerical ability S- spatial perception P- form perception Q- clerical perception K- motor coordination F- finger dexterity M- manual dexterity Mean score of 100. 80-120 is the average range
O*net ability profiler- aptitude test
