Sad to hear that the Northern Grid web site has now gone offline and with it SEN Switcher, the program for children with complex needs that I designed almost 20 years ago.
UPDATE April 18: Moved SEN Switcher to new web server. Please use the link below to run SEN Switcher in your browser. Please update your bookmarks.
UPDATE October 18: SEN Switcher is now available as a free download for Windows PC from our Member’s Area. Choose to download individual levels or the whole program. You will need to register with our web site. Registration is free and takes only one minute.
Hope this helps.
