Human Factors
When flying left traffic patterns for taxiway parallel [Runway] XX with a student pilot; a plane taking off a parallel Runway XX turned an early left crosswind at 300 AGL after we had turned our crosswind at 300 AGL in a helicopter. Upon hearing the radio call; I glanced over my left shoulder knowing their relative location upon climbout. I found them almost directly above and to my left making a left hand turn that was leading into our course. I immediately descended to approximately 150 AGL to build separation from the craft and turned to the right to avoid a collision course. I called out upon the radio to connect with the the other aircraft and no response was received from the other pilot; who I came to find out was a solo student. The plane was flying extremely tight patterns cutting off the flow of helicopter traffic that is typically flying on the adjacent taxiway. With two flight schools based at ZZZ; there is a lot of student traffic. Procedures and policies have been put in place; but lack of situational awareness from students causes a lot of mishaps such as the events of today.
R-22 Instructor reported an NMAC event during landing pattern training. R-22 executed an evasive maneuver to prevent  a collision with a solo student on parallel runway.
