What is a concordance table?

A concordance is an official statistical mapping between two tests, built jointly by College Board and ACT from students who took both exams. It tells you which scores represent equivalent performance, so an SAT total can be expressed as an ACT composite.

Is the conversion exact?

No. The concordance gives the most likely equivalent, but the two tests measure slightly different skills, so the mapping is a statistical best fit rather than a precise translation. Treat the result as a close estimate.

Should I report my SAT or my ACT?

Report whichever is stronger relative to typical admitted students at your target schools. Use this conversion to compare them on a common scale, then choose the one that places you higher.

Which concordance does this use?

It uses the official 2018 College Board and ACT concordance, the current standard updated for the redesigned and now Digital SAT scale of 400 to 1600. Both organizations endorse this table.

Why might colleges see a slightly different number?

Some colleges apply their own internal concordance or superscore policies. The official table is the most widely accepted reference, but always check whether a school publishes its own conversion.

Compare your SAT and ACT on one scale

Applicants often hold scores from both exams or want to know how an SAT total stacks up against the ACT. This calculator uses the official College Board and ACT concordance to translate your SAT total into the equivalent ACT composite, letting you compare the two directly and decide which to report.

How it works

The official 2018 concordance pairs each SAT total with a single ACT composite that represents equivalent performance. The tool stores this mapping in 10-point SAT bands across the 400 to 1600 range and returns the ACT composite for the band your score falls in. Because the SAT is scored in 10-point steps and the ACT in whole points from 1 to 36, several adjacent SAT scores map to the same ACT composite.

Example and notes

An SAT total of 1400 concords to an ACT composite of 31, while 1500 maps to 34. The mapping is statistical, drawn from students who took both tests, so it reflects the most likely equivalent rather than an exact translation. Some colleges use their own internal concordance, so confirm a school’s policy when it matters.
