I noticed that a Schema has been created in the USERS Tablespace but our local rule is that it should be in a Tablespace by itself. In Oracle how do you move a Schema to a different Tablespace?

A schema itself can not be stored nor can have changed tablespace en bloc in any way. In fact, it is just a meta-structucre. Instead - there is DEFAULT TABLESPACE attribute of underlying USER. If you change it, then new objects are created in this tablespace by default (unless you excplicitly specify another one).

In addition, each type of structure (Table/Index/Partition...) has it's own way of moving to another tablespace. (i.e. moving a table does not move indexes built upon it - which would be rather undesirable, because you want to store indexes in another filesystem for better performance). This means, that you will have to move contents of the schema object by object.

Having seperate tablespaces for tables and indexes isn't really considered neccessary for performance, though it can still be done for admin reasons. See this old SO thread, or various AskTom articles. – Alex Poole Jun 20 '12 at 7:02
Also, keep in mind any LOB objects (BLOB, CLOB) have their storage separate from the rest of the table, with only a pointer stored in the table structure itself. If your intent is to move an entire table and its contents, you will need to move the LOB segments independently. "alter table t move lob(y) store as ( tablespace users )" – REW Jun 23 '12 at 4:41

For 10 & 11G, use data pump utility. Follow the tutorial here:

It is the safest if not the best way to do it.

Consider summarizing the key points in the link to beef this answer up a little since links can go stale over time. Another reason is that answers that are "barely more than a link to an external site" may be removed see the FAQ. – Paul White Nov 3 '12 at 10:39
