<p>Quoted from someone else here with a great explanation: </p>
<p>Safety - 90%+ chance of acceptance
High Safety - 80%+ chance of acceptance
Low Match - 75%+ chance of acceptance
Match - 50%+ chance of acceptance
High Match - <40% chance of acceptance
Low Reach - <30% chance of acceptance
Reach - <20% chance of acceptance
High Reach - <5% chance of acceptance</p>
<p>Overall, a safety means that you are likely to be accepted, usually safeties are backup schools. A match means you may be a good fit for the school, and have good chances of being accepted (although not guaranteed.) A reach means that your chances are low, but in some extreme situations you can still “reach” it. The “high” and “low” are simply modifiers of the above classifications to make it a bit more precise. The scale from 100 to 0 percent chance of acceptance would look like:
(~100%) Low Safety - Safety - High Safety - Low Match - Match - High Match - Low Reach - Reach - High Reach (~5-0%) "</p>
