Has P&C Received Ecclesiastical Authorization?

Has P&C Received USCCB Approval?

Only certain types of catechetical texts and materials are eligible to receive a conformity review by the USCCB’s Subcommittee on the Catechism. Principles & Choices is a supplemental curriculum that is not subject to this conformity review. Under the guidelines of the Catechism Subcommittee, a conformity review will only be provided for those supplemental materials “which explicitly and consistently cross-reference an approved basal series.”

Principles & Choices was developed to offer schools and parishes maximum flexibility in implementation. Accordingly, it was not designed to be used exclusively with any one specific basal text or series, since Catholic schools and parishes obviously use a variety of these curricula. Because it is not tied into a specific basal series, a conformity review is not prescribed.

The following excerpt from a statement of the Subcommittee on the Catechism is also relevant to this question:

“It is important to note, however, that not all catechetical texts and materials are subject to a conformity review. The fact that a given item does not appear on the Subcommittee’s ‘Conformity List’ does not necessarily mean that it is has been reviewed and found to be deficient, or that the publisher has failed to submit it.
