What is the duration of the optimal period on which you evaluate the performance of your employees? One year Two years Five years Why?

On a quarterly basis to ensure consistency in productivity and target achievements.

I would prefer the one year span but with associated objectives needed to be achieved vs certain skills level needed for the ocupancy.

Lutfi Qarajahhas beautiful views on the topic. Agreed with that

To evaluate an employee is very difficult but i dont think that it is an exact period of time that tells us about an employee. because people change during the time and an employee that you see as perfect today may change during the time and you will change your mind or vice versa.

Assalam O Alaikum

      if experreinced only few days the employees performance is  check out   and  if new / non expereinced / fresh u trained and given the training   three months to six moth is a grace period in  which  check out   performance  and u watch his ability intrest  . 

  Thanks 

Two years, during the first year, the employee will get busy understanding his job requirements, tasks and getting the required training and it would be a mistake to judge his performance during his first year. After his first year, he supposed to be fully understanding of his job position and his evaluation would be more assessable. 

Thank you for the invitation.

An appraisal is carried out on a yearly basis after a one-to-one basis of mentorship with a supervisor for any of the employee needs for attaining the goals and aspirations of the employee and organisation.  A three month one-to-one helps an employee to set the mark for his performance too.  Companies follow this regime as well.

After two years of work experience with the company the goals should have reached its’ optimal performance.

The employee must know the company rules and regulations as well as routines in a company. 

Performance evaluations, which provide employers with an opportunity to assess their employees’ contributions to the organization, are essential to developing a powerful work team. Yet in some practices, physicians and practice managers put performance evaluations on the back burner, often because of the time involved and the difficulties of critiquing employees with whom they work closely. The benefits of performance evaluations outweigh these challenges, though. When done as part of a performance evaluation system that includes a standard evaluation form, standard performance measures, guidelines for delivering feedback, and disciplinary procedures, performance evaluations can enforce the acceptable boundaries of performance, promote staff recognition and effective communication and motivate individuals to do their best for themselves and the practice.

The primary goals of a performance evaluation system are to provide an equitable measurement of an employee’s contribution to the workforce, produce accurate appraisal documentation to protect both the employee and employer, and obtain a high level of quality and quantity in the work produced. To create a performance evaluation system in your practice, following these five steps:

1.        Develop an evaluation form.

2.        Identify performance measures.

3.        Set guidelines for feedback.

4.        Create disciplinary and termination procedures.

5.        Set an evaluation schedule.

Termination. Explain the reason for the termination but do so briefly and objectively to avoid getting into an elaborate discussion that puts you in a defensive position. Validate the employee as a person, perhaps by giving a positive slant to the employee’s potential in the job market. For example, although an employee might have been a poor file clerk for you because he or she didn’t pay attention to detail, the employee may have a friendly personality that would make him or her a good telephone operator. Also, let the employee know what will become of any accrued vacation or sick leave, pension benefits, etc. Know your state’s laws on these issues. Finally, ask if the employee has any further questions and then assist the employee in retrieving all of his or her belongings and leaving with as much dignity as possible. If you handle termination well, you are less likely to have an employee who wants to “get even” by badmouthing you in the community or seeking legal revenge.

It is also advisable to run the finished system by your attorney to identify any potential legal problems that should be fixed.

A performance evaluation system should be a key component of your practice structure. When implemented effectively, it ensures fairness and accountability, promotes growth and development and encourages a sense of pride in your employees’ contributions to the practice.

Thanks for invitation,

I do believe that, "One Year", is an enough duration period for any expert manager to evaluate the employee performance or discovering his actual talents and real skills.
