I have always found having access to an example or template of what I am trying to create incredibly helpful. For me, it takes away the initial phase of writing a report where I struggle to wrap my head around the entire document and means I can read one section and use it to create a comprehensive and concise document.
Here are some of the templates: Template Lab -
This site has 28 different templates that provide you with examples of several DAP notes ranging from 300 to 2000 words and the option to download a blank template (for those like myself who struggle with structure in word). I would highly recommend reading some of these if you are new to the DAP note methodology to get a good idea of the tone and length you think is most appropriate for your setting.
Sample Templates -
Like Template Lab, Sample Templates will provide you with several templates, with and without exemplar content. They also have links to exemplars of SOAP notes and other forms of progress notes so that you can compare and contrast these layouts and find what is best for your practice.
