Have all the employees undergone an induction programme ? This would be the first thing to do with them.
Regarding training apart from induction, I suggest you to first identify the responsibilities and the job they are recruited for. Incase it is a specific process job which is defined as a particular process in the organisation, in that case you would need to make them undergo a process training specific to the job they are supposed to do.
Incase that is not there, then I would suggest not to go for any training programme right now incase you are thinking on the lines of behavioral areas. Let the new joinees get the feel for the organisation. Let them get tuned into the organisational roles and the job responsibilities. I believe anything less than 6 months would be too early incase their is not an urgent need. Secondly also use Training as a motivation tool for the new joinees. At the time of joining the motivation level is quite high and people are very restless to get on to the the job. Let them feel into the process. A training 6 moths later would be more effective and also be a good motivator for the individuals.
If required some of the behavioral inputs could be covered in brief in the induction programs.
this is just an idea I share, you need to map it with the situations and your organisational requirements.
