The Hubbells moved up to the Junior level both nationally and internationally in the 2006–2007 season. They made their ISU Junior Grand Prix debut on the 2006–2007 ISU Junior Grand Prix circuit. At their first event, the event in Courchevel, France, the Hubbells placed second in the compulsory and original dances and then won the free dance. They won the silver medal behind Ekaterina Bobrova / Dmitri Soloviev by a margin of 0.78 points. The Hubbells were then assigned to their second event, the event in The Hague, Netherlands. They placed third in the compulsory dance segment and then won both the original and free dances to win the gold medal overall by a margin of victory of 1.84 points ahead of silver medalists Grethe Grünberg / Kristian Rand. These two placements combined qualified them for the 2006–2007 ISU Junior Grand Prix Final, for which the Hubbells were the third-ranked qualifiers. Qualifying for the Junior Grand Prix Final had also given them a bye to the U.S. Championships.
