Yo también me inclino por pensar que es un error. Le he preguntado al cliente y no contesta, así que me decidí a preguntar por si a alguien le sonaba...

No hay duda de que el término existe pero Google no arroja ni un solo resultado del sintagma "progressional peers" y dado el contexto proporcionado me inclino por la opción de "typo" ;)

It´s true that "progressional peers" sounds weird. However, progressional does exist and can be used as an adjective, though it´s very rarely used in this form.
Maybe it´s a typo, but we can´t be sure unless the client confirms.
