This is a great little read about how to keep track of assessment that is very quick and easy.  Below are some ideas from the Guide to Combined Grades http://earlylearningcentral.ca/wp-content/uploads/2009/02/Learning-Together-commercial-print-craft-final-copy-195.pdf

Keep a clipboard handy for assessment possibly by subject or learning area–mark it as such–create a class list and produce a 3 column chart with these headings-  

• Three-column chart (Got It! Getting There! Needs Help) to quickly capture student understanding and next steps for instruction.

I keep something similar to this on hand at all times in a folder.  I use the headings Not Evident, Some Evidence, Evident.  Or Needs Improvement, Satisfactory, and Good.  I also keep a column for comments/next steps and a place on the bottom to write notes.

• Laminated folder with post-it notes to monitor ongoing student progress and development of a skill, strategy and/or technique (i.e., I, L, ?).

• Anecdotal notes, one-on-one conferencing and written observations of student understanding in a variety of settings (whole, small-group, partner activities).  I created a table with large blocks and placed each child’s name in one.  This way I can keep track of who I have written notes for and have the subject indicated on the top.  I also keep extra paper on hand if I see/hear a special oral conversation that needs to be noted.
