How to output p value for covariance parameter estimates when using PROC GLIMMIX?

[di_niu0]

Hi All. I am doing a multilevel model using PROC GLIMMIX. 

proc glimmix data=schools method=quad;

         class school_id class_id;

         model  score = class_id / solution dist=binary link=logit;

         random intercept / subject=school_id solution;

run;

Result:  

            Covariance Parameter Estimates 

Cov Parm      Subject         Estimate    Standard Error

Intercept        school_id       0.04852     0.39480             

How do I output the p value for this estimate of parameter?
