On this webpage, you can find the English version of the ADAPT instrument and manual. The Assessing Differentiation in All Phases of Teaching instrument, in which a classroom observation and interview with the teacher are combined, was developed based on extensive research into differentiated instruction. Here you can read our article about the development and validation of the ADAPT instrument. If you want to read our other (scientific) publications about our research into differentiation and ADAPT, click here.

We highly welcome researchers and institutions around the world to collaborate with us and work with the ADAPT instrument. Please do not hesitate to contact us for more information about the use of ADAPT and possible (inter)national collaborations.
