We have been using PandaTree for several months now and we couldn't be happier. My 4-year old is taking both Spanish and Chinese language classes. We love the 1-on-1 instruction and the platform's amazing visuals, catchy songs, and energetic and kind instructors. Her teachers keep her engaged the whole time. She also really enjoys doing her "homework" on the off days by listening to the songs, coloring the coloring sheets, and playing the word master challenges the platform offers in between classes. They really help reinforce the words and phrases she is learning. I have also used PandaTree to assess my two older kids' Chinese proficiency. This is one of the best language learning programs we've used and I highly recommend it.
