Scoring Program

The Scoring Program for the MacArthur-Bates Communicative Development Inventories, Version 2013 (Virginia Marchman © 2013) will run on any MS Windows operating system with Office programs, Access, Word, Excel. (Sorry, no Mac version is available.)
The program is suitable for use by any researcher or clinician who is a regular user of the MacArthur-Bates CDIs (English and/or Spanish), either the short or long forms.

New! Announcing two new versions of the scoring program for use with Canadian and European French (Marchman & Friend, 2015)! Please contact Maggie Friend for more information!

Program Features:

  • It's easy to use! It is easy to hand-enter data into the program using an user-friendly system. Entering the data for a complete CDI takes less time than hand counting!!! Data can be input at the category (e.g., Animal Sounds) or item level. If you are using the NCS-scannable versions of the forms and have an NCS scanner, the CDI program can import files generated by Scantools. (Our scantools application files for English and Spanish CDIs are available upon request.)

    Everything that you need to know (hopefully) about how to use the CDI Scoring program is contained in a handy User's Guide, but please contact Virginia Marchman if you have any questions.

    The program is FREE, but please do NOT distribute it without permission. Potential users of the program are asked to provide their Name, Email Address and Institution for record keeping purposes, and so that we can notify you of potential updates. For questions or more information, contact Virginia Marchman

  • Scores the English (MacArthur-Bates Communicative Development Inventory: Words & Gestures, Words & Sentences) and Spanish (Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Gestos, Palabras y Enunciados) forms. This version also scores the short forms, including Level I (8-16 months), IIA and B (16-30 months), and the Level III (appropriate for children 30-37 months of age).

    Automatically calculates percentiles for key variables which are included in reports to parents or for in-house use. The program also calculates "composite" scores which merge responses from both the English and Spanish CDIs (Pearson & Fernandez, 1994; Pearson, et al, 1993). A file listing these matches is available for download by clicking on the following link:

    Establishes a database of participants which tracks demographic or medical history, CDI data, other administrations (user-defined "Other Admins") and group identifications (user-defined "Selection tags").

    Generates Child Reports and Parent Letters that summarize responses in a user-friendly format. Child report and letter templates to fit a variety of specific situations are currently available in English and Spanish. Templates can be modified to meet your own needs and can be tailored for several sub-populations (e.g., a set for normal language participants, a set for children with SLI).

    Generates "Selected Variable" summaries of data, selecting participants by any criterion and outputting any variable from the CDI and/or user-defined "other administrations" or "selection tags". These can be output into a table (Access) or spreadsheet (Excel) format. Spreadsheets can be imported to statistical packages as needed.
