More than 150 of Dilworth's choral compositions and arrangements have been published—many of which are a part of the Henry Leck Creating Artistry Choral Series with Hal Leonard Corporation.  Additional publications can be found in the catalogs of Santa Barbara Music Publishing and Colla Voce Music, Inc.  Dilworth is a contributing author for the Essential Elements for Choir and the Experiencing Choral Music textbook series, both published by the Hal Leonard Corporation/Glencoe/McGraw-Hill Publications, and for Music Express!

A frequent presenter at local, state, regional and national conferences, Dilworth has conducted 43 all-state choirs at various levels (elementary, middle school, high school), and has conducted 6 regional honor choirs and 4 national honor choirs (ADCA, OAKE and NafME). He has most recently appeared as guest conductor for international choral festivals and master classes in Australia, Canada, Taiwan, Ireland, and China as well as all-state choirs in North Carolina, Oklahoma, Ohio, Arizona and Massachusetts.  He has also led honor choirs for the Central and Southwest regions of the American Choral Directors Association.  International festival and clinic invitations include Canada, Singapore, Austria and France.
