Hello,
This year we purchased VEX Professional Development Package. I am trying to figure out if we need to purchase this each year to access the STEM lessons, Unit challenges, and answer keys. Is this apart of the PD package or is this accessible for free?
Hi @Lauren_Coker! Great question! All of the STEM Labs, Unit challenges and answer keys found in the teacher portal at education.vex.com are free!
However, you can use PD+ and this community to request specific coding solutions or any other questions you may have about the materials. This is an example of that. Accessing PD+ (including this community) is something that renews each year.
Let me know if this helps

It’s wonderful having all the curriculum for free, but to have access to the educational team is priceless. If one of my students or I have a question, its easy to reach out and get the support from the community.
