Hello Phill, it`s me again. How are you doing? 

I want to estimate the standard errors for the itens parameters and examinees scores. To acomplish this task I`m using the following code:

se_estimates <- coef(model, simplify = TRUE, printSE = TRUE) %>%
   
as.data.frame()



Or just:

se_estimates <- coef(model, printSE = TRUE) %>%
   
as.data.frame()




Is it right? There is another way to print/save the parameters/scores SE for further analysis?

Thanks in advance for the answer. 

Best regards,
Flavio

The second approach seems fine to me. It returns a list with the parameter estimates and the SEs.
