The first and most pressing is the concern that overall participation numbers remain stagnant.
There has been annual growth these past few years in the number of kids aged 5 to 12 playing but drop-out rates among teenagers remain high.
Almost half the current number of 13-year-olds playing today won't be playing by the time they are 18 and then there is typically another drop-off in the transition from schools to clubs.
NZR is trying to determine whether a greater emphasis on participation at schools instead of winning and fostering elite players would lead to a reduction in the numbers who give up the game prematurely.
The second key driver of this review is catering for the growth in popularity of rugby with girls.
Girls have basically been ignored until now and those schools which have built successful teams have done so largely on the back of the selfless commitment of a handful of dedicated teachers and parents.
Quite obviously competition structures for girls need to be developed, and investment increased.
There are thousands of new players potentially out there, but they need to be coached, refereed and put in meaningful competitions.
And thirdly there is the question of governance which interestingly is listed as the first thing the review wants to address. During the Herald's investigation in 2013, numerous teachers and principals suggested they felt NZR wanted to take ownership of schools rugby.
Understandably there is resistance to that idea among the schools who feel it would be potentially disastrous to cede control of what is effectively an extra-curricular activity to an external organisation that is largely about promoting high performance, professional rugby.
That resistance is particularly strong in Auckland where a few years ago NZR tried to pressure the 1A competition to open to the best teams from North Harbour.
The idea was rejected by the larger, traditional schools who said it would be wrong to cut out some of the less well-resourced schools.
There was also considerable ill-feeling among principals towards NZR when the national body, with limited consultation, announced there would be compulsory drug testing at the national Top 4 tournament last year.
However, it would seem that NZR wants to pose the question whether it is the right body to take control of all schools rugby and have everyone operating under one system.
