Tk20 stands for “Technology in Kindergarten through Age 20”. It’s an online system administered by UMass that serves multiple purposes. You’ll use it to collect material for your portfolio, complete forms, and submit MTEL scores. After you’re admitted to the licensure program, you’ll need to purchase a Tk20 account (unless you’re a Speech Language Pathology or professional licensure program candidate). Log in to TK20 here.
