The content validity test in this study used 4 assessment criteria, namely Very Appropriate (VA), Appropriate (A), Not Appropriate (NA), Very Inappropriate (VI). The Project Assessment instrument for learning Islamic religious education and morals resulted in 15 indicators being declared valid with an average Aiken index above 0.873.
