To test if all values in a range are at least a certain threshold value, you can use the COUNTIF function together with the NOT function. In the example shown, the formula in G5 is:


Generic formula



At the core, this formula uses the COUNTIF function to count any cells that fall below a given value, which is hardcoded as 65 in the formula:


In this part of the formula, COUNTIF will return a positive number if any cell in the range is less than 65, and zero if not. In the range B5:F5, there is one score below 65 so COUNTIF will return 1.

The NOT function is used to convert the number of from COUNTIF into a TRUE or FALSE result. The trick is that NOT also "flips" the result at the same time:

  • If any values are less than 65, COUNTIF returns a positive number and NOT returns FALSE
  • f no values are less than 65, COUNTIF returns a zero and NOT returns TRUE

This is the equivalent of wrapping COUNTIF inside IF and providing a "reversed" TRUE and FALSE result like this:
