Frequently Asked Questions

Q. Why are you charging for the answer keys and teaching notes?

A. Our organization was originally developed and funded by grants from the Pew Charitable Trusts and the National Science Foundation. We are pleased that the use of case studies and our website have continued to grow significantly since then. However, as a result of decreased funding, increased service, and increased usage of our site, we find ourselves having to charge for the use of teaching notes and answer keys to remain viable and to be able to continue to offer you these materials. You can help ensure that the Center and its work continues - and directly support the development, peer review, editing, design, and publication of new cases on our site, for both yourself and for others - through your subscription.

Q. How much is an annual subscription?

A. An annual subscription costs $25.00 from the time of payment. This fee gives you access to the answer keys and teaching notes for the 700+ cases in our case collection. The cases themselves remain free of charge.

Q. If I am currently registered for an answer key account, what do I need to do to continue to be able to access answer keys and teaching notes for the cases on your site?

A. You will need to go to to pay for an annual subscription to access the answer keys and teaching notes. The cost is $25.00 annually from time of payment. Cases remain free of charge. When prompted, log in with your username and password.

Q. Can students purchase a subscription?

A. No, only teachers can purchase a subscription to the teaching notes and answer keys on our site. We review each application and verify the status of the person applying.

Q. I want to modify your cases to make them more relevant to my students. Can I do that?

A. Yes.  We encourage people to modify our cases. To make that possible, the PDF case files are not "locked." You can copy-and-paste from them to create your own versions, tailoring them to your needs.  For instructions, see Modifying and Personalizing Case PDFs.

Q. I am having problems downloading some of the PDFs on your site. The title displays correctly, but the rest of the letters in the text are replaced with dots and I get a message that says the program "Cannot extract the embedded font." How can I solve this problem?

A. A handful of readers have informed us they have difficulty viewing certain case PDF documents. This seems to happen to files in a subset of the collection, and it appears only to affect people running older versions of Adobe Reader/Acrobat. If you experience this problem, please send an email message with the title of the case to so that we can fix the problem for the next user. More generally, however, the issue can be solved on your end by simply updating to the most recent version of the Adobe Reader/Acrobat available on Adobe's site at

Q. I cannot find a case study that I have used before from your site. 

A. Not all of the cases on our old website have been transferred to our new case database.  We have about 10 more that need to be converted, indexed, and uploaded into the case collection database.  These are listed on our "back catalog" page at, from which you can access them. As we add these remaining "back catalog cases" to the new database, they will be deleted from this page.

Q.  Is there a way to get a complete listing of all of the cases in the case database?

A. Yes. To generate a complete listing, go to the case collection page at   Leave the keyword search box empty, don't set it for any of the other parameters, and just click on the search button.

Q. How do I access the answer keys? 

A.  You can access the answer key through the teaching notes for a case but also directly from the case record.  For example, on this page, you will see an "Answer Key" tab. Click on that and input your username and password as prompted to access the key.  Please Note:  If an Answer Key tab does not display on a case record, it means that there is no answer key for that particular case. Access to the answer keys requires an approved account and paid subscription.

For more information on answer keys, including how to register for a password account, see

Q. I have lost my answer key password.  How can I retrieve it?

A. To retrieve a lost or forgotten password, go to and follow the directions.

Q.  What does it mean that the cases are in a database? 

A.   Our cases are indexed and in a searchable database. Cases can be searched by subject heading, intended audience, type of case/case method, topical area, and keyword. To access the case database directly and begin searching for cases, go to:

Q.  How is access in the database organized?

A.  The central point of access to a case and its various components is the case record. The case record consists of an abstract of the case, a list of learning objectives, and information about the author(s), date posted, format, intended audience, type of case, subject coverage, keywords, and topical area(s), if applicable.  In addition, it is from the case record that you access the case itself, its teaching notes, the answer key (if there is one), and any supplemental materials. From the case record you can also submit and/or read comments on a case. To see a sample case record, go to

Q.  When setting a link to one of your cases for my students to access, which page on your site should I set it to, the case record or the case itself?

A.  For student access, we recommend that you set the link directly to the case PDF, for example to rather than to the case record.

Q. How can I help improve the site?

A.   Send us corrections!  Also, as we continue to improve the case database and its search functions, we are particularly interested in hearing from people with suggestions for added keywords or subject headings to make the indexing on the individual case records describing our cases richer and deeper.  As you use the case database, if you have suggestions (or corrections) for the case records, please send them directly to Carolyn Wright at
