Noun (A) + に則った(2) + Noun (B)
(1)に則り
(2)に則っての
Explanation
に則って is a formal structure used to indicate that an action (B) is performed 'in conformity with (A)' or 'based on (A)'. The basis for the action, (A), is typically an established rule, standard, or tradition. This pattern is formed by adding the particle に to the て-form of the verb 則る, which means 'to conform to' or 'to follow'. As such, the grammar literally means that one action follows a particular standard.
This expression most frequently appears after a noun. When にのっとって is used, it modifies the verb that follows. When にのっとった is used, it directly modifies a following noun.
- どの学校に入っても、その学校の校則に則って行動しなければなりません。No matter which school you enroll in, you must act in accordance with the school's regulations.

Learners should become familiar with both the kanji version (に則って) and the hiragana version (にのっとって), as both are widely used.
The noun (A) that this grammar follows is almost always something that serves as a fundamental standard. This includes things like laws, established procedures, customs, or official guidelines, which provide a clear basis for action.
