If someone is in the second grade or above in junior high school when he or she passes Ikkyu, it is possible for him or her to take a Dan examination (to be held at least three months later) for Shodan in the next Dan examination, but if the student is in the first grade he or she isn't eligible to take an examination for a year after he or she passes Ikkyu, due to age restrictions.
一級受有時点で中学2年以上の場合は次の昇段審査（3ヶ月以上後に実施）で初段を受審することが可能だが、中学1年の場合は年齢制限により受有後1年間は昇段審査を受審することができない。
