this is not a good design..

You basically need to redesign your database schema. This is not a good way to store values. You should have separate tables to store teacher and student records.
   
This is a bad design in my opinion. You should let the database ID be auto generated whenever a record is inserted, you shouldn't be trying to control the unique identifiers yourself.

Instead, you should create 2 tables that look similar to this.

UserInformation Table
Id, Name, UserTypeId
1, "Dylan", 1
2, "Dylans Teacher", 2

User Type Table
Id, Description
1, "Student"
2, "Teacher"

Your UserInformation table should take an identifier for the 'User Type' which will describe the kind of user, e.g. student or teacher. This should be a foreign key to the primary key in 'User Type' table

Now, you don't have to worry about inserting within a particular range of IDs, you just add another field that describes the user. If you need to add more user types (e.g 'Professor' or 'Exchange Student'), simple - just add the record to user types and you can start recording against it.
   
hi there....

if u can change ur DB design change it otherwise take parameter from SP as ROLE(teacher or student) and then insert it based on condition) take last id from @@identity and then insert value with next id...
