Create a list of all the people who helped you with your thesis in any way. This might include professors, advisors, lab assistants, colleagues or supervisors. They may also be part of your personal connections, such as friends, family members or a partner.
Narrow your list to the people you would like to include in the acknowledgements page. There may be people who played some small role in creating your thesis, but you may not feel the need to include them on the acknowledgements page. Acknowledgements have more import if you keep them more exclusive.
Write the acknowledgements paragraph that goes above the names of all the people you would like to thank. This is a short paragraph, but can contain many meaningful and sincere words. To start, you might use phrases such as, "I could not have complete this thesis without ..." or "I am deeply grateful for all those who made it possible to ..."
Single out any key people you would like to thank on their own. For example, if your academic adviser stayed up with you several nights perfecting your thesis or went above and beyond her duty in some other way, you might add a paragraph starting with, "I would like to express a special thanks to ..."
Format your acknowledgements page. Type "Acknowledgements" at the top of the page. Skip four lines. Include your paragraph and special thanks. List the rest of the people you would like to thank. Include this page after the copyright and dedication pages of your thesis.
