Grid rules are the framework that Social Security looks to based on certain factors to say whether you are disabled. They come into play at step 5 of the sequential framework, after it is determined that you cannot do your past relevant work of the last 15 years.
The grid looks at your current age (and your age at onset), your education level, the functioning level of your past relevant work and whether you have skills from that work which transfer to other jobs to determine if you are disabled or to continue to step 5 of the sequential framework to see if there is work you can do.
But what you really need to know about the grid rules are if your over 50, it is easier to find you disabled and it becomes even easier if your over 55. It is also easier to find you disabled the less education you have or if you cannot communicate or read in English. Under the grid rules, if your under the age of 50, you generally must be precluded from all work to be found disabled. But at 50, you may be able to do sedentary work but still be found disabled. And at 55, if your limited to light work or less, a finding of disabled is generally the case.
To understand how the grid rules may affect your case, call for a free consultation.
The grid rules can be found on the SSA website
