	abstract = {This paper has two objectives: (a) to provide a clear description of three methods for controlling the maximum exposure rate in computerized adaptive testing {\textemdash}the Symson-Hetter method, the restricted method, and the item-eligibility method{\textemdash} showing how all three can be interpreted as methods for constructing the variable sub-bank of items from which each examinee receives the items in his or her test; (b) to indicate the theoretical and empirical limitations of each method and to compare their performance. With the three methods, we obtained basically indistinguishable results in overlap rate and RMSE (differences in the third decimal place). The restricted method is the best method for controlling exposure rate, followed by the item-eligibility method. The worst method is the Sympson-Hetter method. The restricted method presents problems of sequential overlap rate. Our advice is to use the item-eligibility method, as it saves time and satisfies the goals of restricting maximum exposure. Comparaci{\'o}n de m{\'e}todos para el control de tasa m{\'a}xima en tests adaptativos informatizados. Este art{\'\i}culo tiene dos objetivos: (a) ofrecer una descripci{\'o}n clara de tres m{\'e}todos para el control de la tasa m{\'a}xima en tests adaptativos informatizados, el m{\'e}todo Symson-Hetter, el m{\'e}todo restringido y el m{\'e}todode elegibilidad del {\'\i}tem, mostrando c{\'o}mo todos ellos pueden interpretarse como m{\'e}todos para la construcci{\'o}n del subbanco de {\'\i}tems variable, del cual cada examinado recibe los {\'\i}tems de su test; (b) se{\~n}alar las limitaciones te{\'o}ricas y emp{\'\i}ricas de cada m{\'e}todo y comparar sus resultados. Se obtienen resultados b{\'a}sicamente indistinguibles en tasa de solapamiento y RMSE con los tres m{\'e}todos (diferencias en la tercera posici{\'o}n decimal). El m{\'e}todo restringido es el mejor en el control de la tasa de exposici{\'o}n,seguido por el m{\'e}todo de elegibilidad del {\'\i}tem. El peor es el m{\'e}todo Sympson-Hetter. El m{\'e}todo restringido presenta un problema de solapamiento secuencial. Nuestra recomendaci{\'o}n ser{\'\i}a utilizar el m{\'e}todo de elegibilidad del {\'\i}tem, puesto que ahorra tiempo y satisface los objetivos de limitar la tasa m{\'a}xima de exposici{\'o}n.},
