Pretty much
The difference to be noted is the standard deviation of the scale you've chosen if you need to compare.

For most IQ tests that a psychologist administers, the SD is 15. So an IQ of 130+ is the top 5%. For most tests that people quote, the SD is 21-23, so an IQ of 140+ is in the top 5%.

This means that most psychologists worth their salt use percentiles to avoid confusion. So you'll usually get a percentile range (eg 75th-84th percentile) which you can then convert to whatever score you "want".

Basic statistics really needs to be covered at school. All I remember is asking people about their favourite ice cream flavour and charting it...
