There is no single score that is good for every purpose. On a common IQ scale centered at 100 with a standard deviation of 15, a score above 100 is above that scale's center. Whether a particular result carries that interpretation depends on the test and its norms.

Separate a comparison from a value judgment

Being above or below a reference average is a statistical description. It is not a judgment of character or a complete forecast of what you can accomplish. The useful question is what the result tells you about the tasks you took and what you want to do next.

For example, someone learning numerical reasoning may benefit more from understanding a repeated ratio error than from moving from one descriptive score band to another.

Three questions before interpreting a result

  • What assessment produced this number?
  • Who, if anyone, is the score compared with?
  • Is the result being used for curiosity, practice or a formal requirement?

These questions prevent a common mistake: applying an interpretation table from one assessment to a different website's score.

A simple scale example

On the reference scale with mean 100 and standard deviation 15, 115 is one standard deviation above the mean. That arithmetic describes a location on the scale. A population percentile additionally requires a justified reference distribution; the number alone does not supply one.

starp's scoring table was centered on a simulated group. Its current average of 100 refers to that calibration group, rather than an established representative human population. You can review the method on the About page.

Choose a useful target

For practice, try a process goal: explain your solution, check all the clues or reduce a particular kind of error. For an external requirement, use the accepted assessment specified by that organization. For personal curiosity, read the result with its limits in view. Each is a clearer target than chasing a number described as universally good.

For the numbers behind a particular result, browse the IQ score guide from 70 to 160. Each page separates the reference percentile from starp’s own scoring context.
