Rivola added that it was not only Schumacher Jr's on-track performances that had put him on Ferrari's radar, but also his conduct out of the car.
"Mick seems very polite and he's not full of himself - so congratulations to his parents," said Rivola. "They did a very good job with him.
"He's very young, and he must manage a very huge media pressure. But he is doing it very well."
Mick Schumacher makes the step up to F3 having finished runner-up in both the Italian F4 championship and the ADAC F4 championship in 2016.
F3 is becoming an increasingly important level of motor racing, as F1 teams trend towards selecting younger and younger drivers; both Ferrari's Sebastian Vettel and Red Bull's Max Verstappen made the jump directly from F3 to an F1 race seat.
The route to the Formula One grid could still be a long and winding one for for Mick, however, with several other drivers ahead of him in the 'queue' for a shot at one of the two Ferrari race seats currently occupied by Vettel and Kimi Raikkonen.
Ferrari last month signed Antonio Giovinazzi - runner-up in the GP2 series, one step down from F1 - as their third driver for 2017.
A chain reaction of promotions could free up space for Schumacher to advance, however, if Ferrari team boss Maurizio Arrivabene remains serious in his uncertainty over the future of four-time champion Vettel.
Schumacher senior raced for Ferrari between 1996 and 2006, a period of unprecedented, record-breaking dominance for the Italian outfit.
Michael won five consecutive driver's titles with the Scuderia (2000-2004) and won 72 Grands Prix in their time together, becoming one of the greatest drivers in the history of the sport in the process.
The elder Schumacher is still recovering from injuries sustained in a skiing accident in December 2013 and there is still little-to-no news of his progress.
