Thank you, I 'll write if I get answer from our Head Office HR) if HR will be available)

Darryl, I think it is more results oriented than that. Of all the Full Time Employees in the company, some work very productively and others less productively. The High Potentials are employees that are very productive, and the ratio is the number of these high performers as a portion of all employees. I am just guessing-I am not sure what this paragraph deals with. As you suggest, it can still mean the number of excellent hires form the total pool of potential employees. I am not familiar with HR Speak.

wow! that's a good one. so potentials, I assume, are people who are in the hire process. total quantity = total number. if someone has high potential, it means they have a good chance, but in this case, it is a noun meaning number of people who have a good chance. FTE means Full-time employee. So the ratio is the number of people who show high potential to the Full time employees over the year. The ratio will measure the success of the hiring process. for instance, if it is 40 out of 50, then almost everyone who was very good was hired and became an employee. Does that make sense?

This is a rarefied type of language. It is vague, but means that potentials (for growth, profit, sales, etc.) have been divided into high, low or medium, and the frequency of the High Potential group (number per year, per quarter) is a hard number (total quantity). It just means "number of times a year that we see the highest possibility for something hqppening".
