One of the main references for this kata is Nakayama Sensei "Best Karate" Volume 6. Nakayama states that Bassai Dai along with Kanku Dai are representative Shotokan Kata. From Bassai can be learned composure and agility, strength and change, fast and slow techniques, the dynamics of strength, turning disadvantage into advantage and changing blocks. Bassai Dai is often selected for Shodan gradings and is regularly selected by the examiner for Nidan and Sandan gradings.
