Excel spreadsheet automatically adds up your hours of all the professional development you attend as the year progresses. This spreadsheet is designed for more than 10 years from now and more years can be added easily by copying and pasting. The file can be downloaded to your computer, a cloud drive, or your smartphone. It can be uploaded to a spreadsheet program and edited from any device you have a compatible spreadsheet program installed. I use mine on Google Drive and access it from the Google App "Sheets". I access it from my Android phone, iPad, and laptop as soon as I attend the PD. You will never have to ask fellow colleagues about the dates or hours of PD you have attended. You'll never again have to search through your calendar for the entire year for all your PD. It will be at your fingertips at all times to print at the end of the school year AND save every year. Great way to stay organized! 48 pages over 10 years ready-made with formulas total your hours as you type.
