Since our site was accepted into google news a week ago, only 1 of our articles have been crawled, our sitemap is valid and working, we have since posted about 20 articles, but only 1 has inputed into the google news search.
The title says that the articles are not being crawled. Does that information come from your server logs? If they're not even crawled, then being indexed or not is a moot point, since Google doesn't even see the content to rule on something like grammar or quality.
Not being crawled sounds like a technical issue to me. I've read that your News Sitemap must not be a regular sitemap (see this page [google.com] for the details) and Google also should not be pinged through Webmaster Tools.
Once you are accepted into the Google News program as a publisher, the bot should be asking for your News Sitemap several times a day - as long as they've got a correct URL for it.
Since our site was accepted in the Google news, only 1 has been craweled, the way i know is i search site:example.com in google news and it comes up. I did setup a special sitemap for the google news that is separate from the standard sitemap.

"We've recently noticed that at least since June 3rd we haven't added any new News sitemaps to our crawl. Please be assured that our engineering team is working to find a solution. We apologize for any inconvenience and hope to resolve this issue in the near future."
