Hidemi Suganami (1983) agreed with Jones on the existence of a distinct school and called it as “British institutionalist approach”. He identified five factors that united the authors of this approach:

1) aspiration to werthfreiheit (morally neutral analysis),

2) rejection of behaviourism or scientism,

3) reliance on sociological methods (institutional analysis),

4) unity and specificity of the states- system (autonomy of IR)

5) rejection of utopianism.

Suganami however disagreed with Jones and considered the contribution of the School to be significant and consequently he did not call for a closure.
