Chapman (1990) stated that their schools implemented the Illinois Writing
Program combined with an authentic writing assessment, portfolio, to improve their
students’ writing. Teachers were trained to use the portfolio as an educational tool for
instruction of writing skills from original site customwriting.io. Students compiled a chosen collection of writing throughout
the school year to be entered in the portfolio. The students’ collection of writing reflected
a varying degree of writing skills fi-om the beginning to the end of the school year.
