A page is different from a post (see other help article "adding or editing a Post")
Please note: you may need admin access rights to be able to publish new pages.

To publish a new Page
1. Log in to WordPress admin, click on Pages on the left menu, then “Add New”.
2. Choose a title. Remember that the title you choose will be the website page URL (address) – so keep it simple.
3. Next, click into the large writing area and start writing your text. You can use the formatting options if you wish.
4. Once you are happy, on the right, under Publish you will see Save Draft, Preview or Publish as well as the option to password protect the page, or to set a future publishing date. It’s recommended to Save Draft before publishing – obviously the latter means it is live on your site. Once you’ve saved the draft, you’ll be asked if you want to view it – allowing the option to check for problems. There’s also a spell checker on the formatting bar
5. If relevant, select the correct page parent (located under Publish section) to publish your page under (if there are multiple to select, choose the one that’s most appropriate for your post – e.g. news or featured).
6. When you’re fully content, you can publish to the live site – then go and check to make sure everything is as you expected.
You may also need to add the new page to your menu bar. You can do this if you admin rights by clicking on the Appearances / Menu link on the main WordPress left hand side menu.
