Another policy commonly used by 4.0-scale schools is to mimic the eleven-point weighted scale (see below) by adding a .33 (one-third of a letter grade) to honors or advanced placement class. (For example, a B in a regular class would be a 3.0, but in honors or AP class it would become a B+, or 3.33).
The 2022 scores were calculated by adding scores from each school in a district, then dividing by the number of schools with students in grades three through eight. The 2023 PSSA report includes ...
Scaling is the process that adjusts VCE study scores into ATAR subject scores. The Victorian Tertiary Admissions Centre (VTAC) adjusts all VCE study scores to equalise results between studies with stronger cohorts, and those with weaker ones. Contrary to common perception, scaling is not based on the difficulty of the subject, as each study ...
The Programme for International Student Assessment (PISA) is a worldwide study by the Organisation for Economic Co-operation and Development (OECD) in member and non-member nations intended to evaluate educational systems by measuring 15-year-old school pupils' scholastic performance on mathematics, science, and reading.

In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.
The test takes 45–90 minutes to administer depending on the age of the participant. The mean score for the WIAT-II is 100 with a standard deviation of 15, and the scores on the test may range from 40 to 160. 68% of participants in the UK standardisation sample obtained scores of 85-115 and 95% obtained scores of 70-130.
The reason for the choice of the number 21.06 is to bring about the following result: If the scores are normally distributed (i.e. they follow the "bell-shaped curve") then the normal equivalent score is 99 if the percentile rank of the raw score is 99; the normal equivalent score is 50 if the percentile rank of the raw score is 50;
Standard-setting study is an official research study conducted by an organization that sponsors tests to determine a cutscore for the test. To be legally defensible in the US, in particular for high-stakes assessments, and meet the Standards for Educational and Psychological Testing, a cutscore cannot be arbitrarily determined; it must be empirically justified.
