Again, perhaps the most important element is that therapeutic assessments have a clinical impact about the equivalent to a similar period of therapy or counselling.
A Psychological Assessment involves the planned use of interviews (generally semi-structured) and specific psychometric assessments (tests) to answer questions highlighted in a referral.
Pre-treatment evaluations, particularly if you know a patient has been referred to you because of limited success in previous treatment or the patient has complex problems/presentation; When treatment has stalled and psychological assessment can be used to identify the factors limiting progress, and;
The interview and test process engages and empowers; it communicates a genuine respect for the patient and has them as an integral part of the process rather than just the ‘subject’ of an assessment. Testing lends legitimacy to an assessment process.
Psychiatric assessments are based on a bio-psycho-social approach and this means that whilst structured assessments are valuable, they may not tease out the interplay between the bio-psycho-social elements (i.e the causality).
Standard scores are helpful because they allow comparisons of a child's performance on different types of tests. They also help estimate a child's strengths and weaknesses compared to their overall ability and allow estimation of a child's skills on a test compared to other students their age or grade level. When parents first become involved in ...
Standard scores are helpful because they allow comparisons of a child's performance on different types of tests.
Percentile scores show how a student's performance compares to others tested during test development. A student who scores at the 50th percentile performed at least as well as 50 percent of students his age in the development of the test. As you will note in the table below, a score at the 50th percentile is within the average range.
Test developers calculate the statistical average based on the performance of students tested in the norming process of test development. That score is assigned a value. Different performance levels are calculated based on the differences in student scores from the statistical average and are expressed as standard deviations .
Standard deviations are typically used in the norm-referenced assessment to establish a scale for determining the significance of differences between scores. These differences are used to determine whether scores are average or significantly below or above average. Standard deviations and standard scores are one of the most common ways ...
To understand the meaning of other test scores, your child's special education teacher, counselor, or school psychologist can provide you with specific information on any tests your child takes in school.
Although all test scores should be considered estimates, some are more precise than others. Standard scores and percentiles, for example, define a student's performance with more precision than t-scores, z-scores, or stanines.

The purpose of testing is to obtain a score for an examinee that accurately reflects the examinee’s level of attainment of a skill or knowledge as measured by the test. Since instructors assign grades based on assessment information gathered about their students, the information must have a high degree of validity in order to be of value.
Item validity refers to how well the test items and rubrics function in terms of measuring what was intended to be measured; in other words, the quality of the items and rubrics.
Reliability refers to the degree to which scores from a particular test are consistent from one use of the test to the next. Validity refers to the degree to which a test score can be interpreted and used for its intended purpose. Reliability is a very important piece of validity evidence.
A test score could have high reliability and be valid for one purpose, but not for another purpose. An example often used for reliability and validity is that of weighing oneself on a scale. The results of each weighing may be consistent, but the scale itself may be off a few pounds.
