The SMOG (Statistical Measure of Gobbledygook) is used routinely by some organizations
(CSAP Technical Bulletin: You can prepare easy-to-read materials, 1994). The SMOG is an
efficient screening tool if you want to do a quick assessment of numerous documents, but it does
not discriminate well at lower grade levels (sixth or below). Write It Easy-to-Read (Root &
Stableford, 1998) advises against using the SMOG if you are developing low literacy materials.
